"Pursuits of Perfection" wooden puzzles, circa 2006
A longtime 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.

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.


The gallery did sell one or two of the Diagonal Star puzzles seen in the postcard promo image, and then I promptly sold all of the rest of them as a single lot to the collector 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 endeavor. 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 take advantages of improvements I've made to my technique in the years since. 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 do not like the way that blurry ink looks on the wooden pieces, which are supposed to be as close to perfection as possible. As such, none of the puzzles in the Pursuits of Perfection edition were ever 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, as can be seen in the photos.

This petite 6-piece puzzle-cube is only 1.8" (4.6cm) across, yet it packs a mighty punch of tactile pleasure in your hands. It's one my very favorite design variations in this whole Stewart Coffin genre. The fit is currently slightly loose, but that might be due to the current winter weather in my workshop.

    excellent condition, exceptionally nice wood grain. All 12 major pin joints have been serviced and glued.
The flame woodgrain pattern in the Palisander rosewood is exceptionally nice on most every surface of the puzzle, inside and out. I still love the contrast in tone that comes from the European olivewood tip pieces even though they have darkened somewhat over the years as compared to the circa 2006 photos.

The olivewood is somewhat soft, so great care must be taken to not chip or dent any of the namesake twelve points! Currently one of those olivewood tips has a small chip, and another one has a barely noticeable ding, yet they are so small that I do not think they detract from the overall stunning beauty of this showpiece puzzle.

This is one of Stewart Coffin's most difficult puzzles in the genre of "shape shifters" which have multiple symmetrical configurations possible. All of the photos of this bocote wood version are showing it in the namesake Star-of-David configuration, however others are possible too. You can see photos of those other configurations here.

Even once you know what shape you are trying to make, it is still hard to get the pieces assembled because for most of the solutions the axis of disassembly does not coincide with the axis of symmetry. Truly devious, yet extremely satisfying when you get it right and suddenly order emerges out of chaos!

    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 records, the looseness and chipped tips were problems right from the beginning for this particular puzzle. I suspect it has something to do with the verawood being tricky to work with.

I serviced all of the friction pin joints and added dabs of superglue in there in an attempt to help it fit a bit more snugly. This helped, but didn't really solve the issue completely.

Despite the chips and fit, it is still a lovely puzzle design, rendered in one of my very favorite woods. You can see in the photos how the woodgrain has a ropy iridescent yellowish-green color which shimmers with blue hues in places.

The puzzle itself is super cool because there are two solutions and both can disassemble on each of the four axes, or all of them simultaneously.

    good condition. the orange cocobolo has substantially darkened over the years as compared to the original photos. one of the ebony pieces has a noticeable chip in it. All pin joints have been glued. fresh coat of ren-wax. excellent fit and finish.
This is a fun color symmetry puzzle, very much like all of my new Haeckel Sphere variations insofar that all of the pieces are the same shape and yet the colors of the different woods are oriented so there are multiple ways to assemble these pieces which have color symmetry.

The bright orange hue of the cocobolo seen in the circa 2006 photos has substantially darkened (as seen in the circa 2025 photos) and now it looks somewhat half-way between the hues of the other two dark woods (Macassar ebony and Palisander rosewood) so unfortunately the puzzle loses some of the contrast punch from a color symmetry standpoint. The Palisander rosewood pieces are the same fantastic woodgrain as seen in the more expensive of the two Twelve-Point lots.

There's a noticeable chip in one of the ebony pieces (It's clearly visible in the main photo) and there are also occasional other minor dents and dings along some of the edges of the pieces, which indicate that this particular puzzle has probably been played with a lot over the years.

I made several matched sets of these for the Pursuits of Perfection series, but this particular lot is just half of a set (only the Diagonal Burr) so I need to see if I can get a copy of the Pseudo-Notched Sticks) to go along with it. As such this lot is sort of on hold but if you are interested let me know. I also have another, newer lot of the matching set which I need to post on here. The photo shown here is circa 2006

    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.

    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 something like a coin, ring, or folded banknote. It comes with a matching 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 very difficult puzzle has a hollow space inside big enough to hold something like a coin, ring, or folded banknote. It comes with a matching elegant display stand which is also a challenging puzzle! Both of these puzzles require a lot of dexterity to solve.

  • The sphere is 2.5" diameter
  • The hollow cavity is 1.3" diameter
  • The total height (on top of the stand) is 3"

    Getting this hollow sphere apart is not easy, and getting the six pieces back together again is even harder! There's room inside to hold a small trinket like a coin or a ring.

    This is based off Stewart Coffin's Cluster Buster puzzle, but with modified geometry to make it spherical.

    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.

  • Description
    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.
