This is wild. The Earth Puzzle is a 442-piece jigsaw puzzle with a difference: based on an equal-area icosahedral projection, the puzzle can be built from any starting point, and in any number of configurations: there is no defined centre or edge. One of Nervous System’s infinity puzzles (one for the Moon is also available), it costs $120 and (at the moment) ships in three weeks (so if you’re shopping for the holidays, get on it). All is explained at Nervous System’s blog. [Kenneth Field]
