The team over at Nervous System recently designed this fun Infinite Galaxy Puzzle that tiles continuously in any direction. Pieces from the top can be removed and added to the bottom, and likewise from side to side. So regardless of where you start the puzzle can continue in a seemingly infinite series of patterns. Each puzzle is printed with satellite imagery obtained from NASA and includes a few themed pieces like an astronaut, shuttle, and satellite. Apparently the puzzles were wildly popular and are now available as a pre-order for 2017.
