Puzzle wizards Nervous System (previously) explore the expansive qualities of earth and space in two new mind-boggling puzzles. The Infinite Earth puzzle includes 442 pieces, and the Infinite Moon has 186. Each can be rearranged in virtually an unlimited number of times. The math behind the magic is an icosahedral map projection, which applies the topology of a sphere without the traditional boundaries. You can learn more of the math behind the transposition from sphere to puzzle on Nervous System’s blog. Nervous System individually prints and laser cuts each puzzle on birch plywood in their Somerville workshop. You can find the Infinite Earth and Infinite Moon puzzles in The Colossal Shop!
