"Pursuits of Perfection" wooden puzzles, circa 2006
An old collector friend of mine recently got in touch with me to find out how I was doing with the cross country move, and to see if there's anything that he can do to help me along the way. He ended up gifting me back some puzzles of mine that he's had in his collection these past 20 years, instructing me to sell them and use the money to keep pushing forward with my moving plans. Such a sweet gesture! The story behind these puzzles is that back in 2005 I had the idea to try selling my work through an art gallery, and so arranged a hometown solo show at the Pacific Grove Art Center which I called "Pursuits of Perfection". I spent the better part of a full year fabricating over 100 copies of various Stewart Coffin style puzzles for the purpose of displaying them behind glass in an attempt to market my work to art collectors in general, rather than puzzle collectors per se. Over the course of this project, I took my craftsmanship to a whole new level of perfectionism by developing a new fabrication technique which uses CNC drilled holes and friction fit steel dowel pins in order to join the individual blocks of wood together rather than glue. The whole thing was a big experiment, and in the end I came to a few conclusions:

  • The pin technique is great, but I should have used glue in addition to the steel pins.
  • No other sales agent will ever be as good as I am at explaining / demonstrating how these puzzles work.
  • The "fine art" industry is kind of a scam.
  • All of the extra effort that went into the show itself (above and beyond simply fabricating the puzzles) was not worth it in the long run, aside from an ego boost.
  • I could have boosted my ego with just one puzzle behind glass, rather than 100 of them.


At the end of it all, the gallery sold one or two of my least expensive pieces, and then I promptly sold all of the rest of them as a single lot to the patron who helped me finance the project. There were naturally some puzzles in this group that turned out better than others, yet they all hold a special place in my heart because of the time and attention to detail that went into the whole project. In many cases, these puzzles were the finest examples of my craftsmanship of certain designs, several of which I have never reproduced since.

As to be expected, these puzzles have "aged" over the course of the 19 years which have gone by since I first made them, yet their condition is still overall quite excellent aside from that the vibrancy of some of the wood grain colors has faded with time. I've refurbished them all prior to listing them for sale here, which means specifically that I've pulled apart the pin joints and added glue in order to address that lesson I learned along the way. I've been somewhat selective about which pin joints I've serviced in this regard, making the decision on a case by case basis as needed. I've put notes in each listing about what degree of refurbishment work I've done.

In addition to coming up with the pin technique over the course of working on this project back in 2005, I also decided that I wanted to stop signing my work with pen/ink because I did not like the way that it looks. I felt like I would be "defacing" the puzzle piece with blurry handwritten pen-strokes, and so none of the puzzles in the Pursuits of Perfection edition are signed or marked in any way. In the years following, I experimented with laser engraving the puzzle pieces instead, but eventually settled on providing separate certificates of authenticity with each puzzle so that I could still physically sign something without compromising the perfection of the puzzle itself.

Part of the refurbishment process includes that I've made new certificates of authenticity for each of these puzzles that I'm selling here.

    This puzzle is in fair condition. There are chipped tips on several of the pieces, and also the overall fit is somewhat loose.
According to my memory and spreadsheet records, the looseness and chipped tips were problems right from the beginning for this particular puzzle, so I recently went ahead and pulled apart all of the friction pin joints and added dabs of superglue in there before reassembling it, in an attempt to help it function a bit more smoothly. Even so, it's still not the best example of my craftsmanship at full potential, yet still a lovely artpiece rendered in one of my very favorite woods.

Currently accepting pre-orders with $200 down payment to hold your reservation, and estimated final cost between $250 - $350 plus shipping extra.

I need to get at least 100 total pre-orders on this project (which would be 50% of the number of Get in the Spirit puzzles that I've sold) in order to have this project make financial sense to pursue. If I cannot get that many pre-orders then I will cancel this project and refund the deposit money.

As of December 1, 2024 there are 53 pre-orders so we are only 1/2 of the way to that minimum 50% threshold. Please pass the word around to other puzzle collectors to help reach the mark.

plastic puzzles
Here's a list of all of the 3D printed plastic puzzles that I have in stock for sale. Several collectors have asked me this past year why I "switched over" to 3D printing, instead of focusing on the woodworking that I'm so well known for. Here's some thoughts to share on that topic:

  • I love how 3D printing allows me to share some of my best design ideas with people in a way that is detached from the "preciousness" of fine-art collectible objects.
  • Having a portfolio of work that's always available and in stock lets more new folks enjoy my designs.
  • I think that people can more easily enjoy puzzle designs as toys when they know they're not super expensive / afraid to break something.
  • I get personal satisfaction from having such a broad selection of my work in active production, and available to such a broad audience due to the low cost.
  • I haven't stopped woodworking.
  • I also do CNC metal machining in addition to woodworking.
  • Admittedly, less of my time gets put toward woodworking or machining projects when I'm also running a 3D printing production operation.
  • Running the 3D printing production operation helps me finance the other stuff that I do (wood & metal) because:
    • 3D printing machines run unattended for long stretches of time, which facilitates my multitasking.
    • I can do "lean manufacturing" which allows me to adapt and pivot my approach as needed without sacrificing any existing production plans.
    • The machinery is cheap and also easy to resell, which makes it quick to scale up/down production output as needed.
    • It gives me an income source that does not depend upon my having an industrial workspace, which has been helpful during recent workshop moves.
    • It's a backup plan in case I ever lose my fancy workshop, for whatever reason.


With all of that said, I am proud to present the following puzzles. Please see the contact page for my email address. Please email me to place orders.

When I first started selling variations on my original Barcode Burr puzzle, I came up with this "Master Set" which included a few new ideas of mine, as well as some of Derek Bosch:



At the time, these were the only variations that I had come up with. These sets came with two sets of body pieces preinstalled with black and blue insert pieces (Barcode Burr and CoordiCode Burr) and preassembled so that you get a chance to do these ones as disassembly puzzles rather than assembly puzzles.

I also sold an "upgrade kit" that omitted the preassembled Barcode Burr if you'd already purchased of those from me.

In the first few versions of this master set that I shipped out, I included an extra "copper" colored body piece so that you could opt to have piece #1 look different than the rest in order to make solving easier. Eventually I stopped doing this in favor of offering rainbow body piece kits as separate items to purchase.

After selling a few dozen Master Sets like this, I came up with several new coordinate motion designs such as:



In keeping with tradition, and new copies of the "Barcode Burr Master Set" that I sell will come with everything needed to try all of the puzzles, but minimal duplication of shared pieces so that you can save money and recycle shared parts between variations. Here is the list of parts that you'll get with a new purchase:

  • Barcode Burr preassembled puzzle with standard silver-gray body piece color (black inserts)
  • GreenCode Burr #1 preassembled puzzle with standard silver-gray body piece color (green inserts)
  • (1) bag of (9) green inserts, for other GreenCode Burr Master Set variations
  • CrossCode Burr #1 preassembled puzzle with rainbow colored body pieces (white inserts)

    All the parts you need to try all four members of the GreenCode Burr family.
This set comes with an assembled CrossCode Burr #1 plus a plastic bag of extra parts so you can mod the puzzle into all four members of the CrossCode Burr family. Please note that CrossCode Burr #5 is not included with this set.

Hex wrench and instructions cards are included.

Click below for "More Info" about this item.
This set includes all of the white colored insert pieces required to make the following puzzles:



This kit comes with one set of body pieces preinstalled with the CrossCode Burr #1 inserts, and preassembled so that you get a chance to do one as a disassembly puzzle rather than an assembly puzzle.

Whereas the GreenCode Burr Master Set gives you 4 variations while keeping 75% of the green pieces the same (small bag of extra parts) the members of this CrossCode family don't share any noteworty pieces beyond the most basic double-pin ones, thus this Master Set comes with larger bags of extra parts.

If you want to spend more: I sell "display upgrade kits" of white insert pieces that contain the 5 ones which are the same between each variation, so that you can have multiple variations assembled simultaneously. You'll need to have an extra sets of body pieces too.

If you want to spend less: I sell this set of white insert pieces as a standalone upgrade kit that does not include any body pieces in case you already have enough of those and don't mind recycling components from one to the next as you try each member of the Barcode Burr family.

If you want to maxx-out your display shelf: This master set + 3 display upgrade kits + 3 sets of body pieces will let you have all four CrossCode Burr variations assembled at once. Honestly though, if you want to go this route then you might as well just buy all four of the individual preassembled from me so that you get to experience them all as blind disassembly challenges as your first experience of them!

This set includes all of the green colored insert pieces required to make the following puzzles:



This kit comes with one set of body pieces preinstalled with the GreenCode Burr #1 inserts, and preassembled so that you get a chance to do one as a disassembly puzzle rather than an assembly puzzle.

On of the interesting things about this family of "GreenCode" designs is that they all share 75% of the same insert pieces, so the only difference between them is which version of maze path "tab" inserts gets installed on pieces #1-3. Another interesting thing is that for each of the four design variations, all three maze path tab inserts are identical. The nature of how these design variations share so many of the same pieces allows this master set to only need 9 extra insert pieces beyond what comes preassembled in order to get 3 more puzzle challenges.

If you want to spend more: I sell "display upgrade kits" of green insert pieces that contain the 9 ones which are the same between each variation, so that you can have multiple variations assembled simultaneously. You'll need to have an extra sets of body pieces too.

Honestly though, if you want to go this route then you might as well just buy all four of the individual preassembled from me so that you get to experience them all as blind disassembly challenges as your first experience of them!

    The original version, preassembled and in stock in two versions (standard and rainbow) at a lower price than the other variations that are based on this award winning classic.
This award winning interlocking burr puzzle has an binary solution sequence, and is loads of fun to play with. There are three versions available which are all identical puzzle geometry yet they get progressively easier to solve depending on how heavily they are color-coded with rainbow piece components:

  • standard has silver-gray body pieces and black inserts
  • rainbow has color-coded body pieces and black inserts
  • double-rainbow has color-coded body pieces and matching color-coded inserts

    This very difficult puzzle has a hollow space inside big enough to hold a coin or ring, and comes with an elegant display stand which is also a challenging puzzle!
Based on Stewart Coffin's Cluster Buster, and inspired by an ex-girlfriend of mine, this "Ball Buster" puzzles comes on a "Nut Buster" display stand, which is also a challenging puzzle. Both of these puzzles require a lot of dexterity to solve.

    This set of three stellation puzzles are inspired by Stewart Coffin designs.
These puzzles arrive to you scrambled up, so you get the extra puzzling challenge of figuring out how to unscramble them and assemble each progressively more difficult stellation.

Here's a fun set of all three stellations of the rhombic dodecahedron, inspired by previous wooden editions I've made such as the IPP29 stellation sets but instead of using Stewart Coffin's original designs for Permuted Second Stellation and Permuted Third Stellation puzzles, I've slightly modified the piece geometry in order to allow them all to 3D print easily. My version of the third stellation is very similar to Coffin's however my second stellation is medium difficulty compared to Coffin's version. A benefit to making the middle puzzle is that it provides a nice ramp-up of difficulty going from smallest to largest puzzle.

I like to deliver these puzzles to customers in the "scrambled" state where one puzzle is solid black, one is solid white, and one is solid accent color. As such, the first three puzzles to solve are those of figuring out how to get these funky looking structures disassembled (not easy). The fourth puzzle (easy) is to sort all 18 pieces to figure out which ones are supposed to go together. From that point, the next three puzzles to solve are getting each stellation assembled correctly.

    Any member of Barcode Burr family is available in either the standard version (silver-gray body pieces) or rainbow version (color coded body piece) for easier solving experience.
I've come up with many variations to the Barcode Burr puzzle, most of which are more difficult than the original. I've color-coded the different sets to help distinguish them from one another:



Each puzzle is available in two versions:

  • standard has silver-gray body pieces
  • rainbow has color-coded body pieces


The standard version makes for a more difficult puzzle solving experience because you cannot tell which piece is which, whereas the rainbow version helps you tell the pieces apart and easily identify the one you're looking for.

Each puzzle come assembled, except for QuadCode Burr which comes disassembled unless you want to pay an extra $50 assembly fee.

    comes with 12 screws and a hex wrench
The reason why you might want to buy this item is if you've already got some version of a Barcode Burr Master Set and want to be able to have more puzzles simultaneously assembled at once. There are two options available:

  • The standard set has "silver gray" colored pieces.
  • The rainbow set has each piece in a different color.


The standard set makes for a more difficult puzzle solving experience because you cannot tell which piece is which, whereas the rainbow set help you tell the pieces apart and easily identify the one you're looking for.

Each set comes with a dozen attachment screws and a hex wrench.

Click below for "More Info" about this item.
One of my design goals for the family of Barcode Burr designs was to have customers be able to try all of the variations at minimal cost by being able to swap out the color coded insert pieces onto the same corner piece body components so as avoid purchasing so many duplicate pieces. If people want to have more variations assembled simultaneously then more body pieces (and attachment screws) are needed.

The "standard" color scheme that I've always used is with each of the 6 pieces being of the same silver-gray color which looks nice and makes for a tricky solving process because it's so easy to "get lost" however I also offer the "rainbow" color scheme so that people can color-code the pieces in order to make the solving process easier to visualize.

    Any variation you like in whatever color scheme you fancy
If you've already got the Haeckel Sphere Set #1 and Haeckel Sphere Set #2 and want to fill out your collection with some of the other available options, you can custom order them "a la carte" with whatever color scheme you like.
This family of design variations are all stellated variation of Stewart Coffin's "Jupiter" puzzle. In addition to the stellation itself, I've made some aesthetic tweaks to the shape of the pieces in order to give it an organic feeling, somewhat inspired by Ernst Haeckel's 1904 lithograph "Blastoidea" which depicts various members of the sea urchin family.

From a strictly geometric perspective, all 12 pieces of each version have the same 5-fold rotationally symmetric shape as each other. Assembly is tricky to figure out at first if you're not familiar with this kind of puzzle, yet it's not especially difficult to do once you've done it a few times. There are a few fun Ah-Ha moments in this process which include elements of sequence and dexterity challenges.

Coffin's Classic 6-color system (dodecahedral symmetry)
Coffin's Classic 6-color system (dodecahedral symmetry)


The true beauty and puzzling challenge from solving a Haeckel Sphere comes from the standpoint of color symmetry. Stewart Coffin's published literature on the topic of the Jupiter puzzle seems to steer readers toward a particular coloring scheme where the 60 sticks (of wood) are divided into 6 groups of 10 each, and arranged so that every parallel stick is of the same color, as seen in this example image of the "preferred configuration". There are 4 other solutions to Coffin's classic 6-color version of the puzzle which also have color symmetry, yet do not have parallel sticks matching. Finding all 5 solutions is a fun challenge, and it could be said that the puzzle is not truly "solved" until all 5 solutions have been found. One of the satisfying aspects of solving each color symmetry challenge is that the puzzle itself takes on a whole new aesthetic with each new configuration, and sometimes the most pleasing of the five options is not necessarily the "preferred configuration" which I would define as the one which is easiest to visualize ahead of time due to having like colors touching as much as possible.



6-color cubic symmetry
6-color cubic symmetry


One of the really interesting things about the geometry of this Haeckel Sphere is that the underlying triacontahedral structure has its own icosahedral and dodecahedral symmetry, as well as several ways to get cubic and tetrahedral symmetry. All of these different versions take advantage of different of those geometric symmetry systems in order to define the color symmetry, so for example there are three different versions of the 6-color Haeckel Sphere. The classic version, as show above in a rainbow colors, has symmetry based on the dodecahedron, whereas this earth-tone version to the left has symmetry based on the cube.



It's somewhat tricky to objectively rank all of the variations from easiest to hardest, so instead I've picked out two groups of four which I think represent a nice selection of my favorites. Scroll down to the bottom of the page to see more details about Haeckel Sphere Set #1 and Haeckel Sphere Set #2.

    Six similarly shaped pieces slide in and out from one another along unexpected diagonal directions of motion. None of the internal mechanisms are visible, yet the sequence of movements follows a logical binary pattern whereby the ability to move, or remove individual pieces from the assembly is dictated by two simple rules which, once understood, make this puzzle fun and easy to play with.
