These are my favorite four versions of the Haeckel Sphere puzzles, showcased below with cute named coloring schemes:

• 5-color checkered Haeckel Sphere (moonrise)
• 3-color Haeckel Sphere (fireball)
• 4-color tetrahedral Haeckel Sphere (mint chip)
• 2-color checkered Haeckel Sphere (deck the halls)
