Infinite Galaxy Puzzle From Nervous System
Usually around this time of year, I buy my mom a puzzle for the holidays. But I will probably skip Nervous System’s Infinite Galaxy Puzzle, since it’s designed to be a puzzle like no other—one with no definite shape or endpoint, just like the universe itself (maybe?).
I’ll be honest, much like my mom I’m helpless to try and understand the Infinite Galaxy Puzzle or how it works. So I’ll let the MIT eggheads at Nervous System explain how the puzzle works themselves:
“Topologically, the Infinite Galaxy Puzzle maps to a Klein bottle, an impossible 3D shape where the inside and outside are mathematically indistinguishable. What this means is that it tiles with a flip. Pieces from the right side attach to the left side but only after flipping over. Just like the Klein bottle’s surface has no inside or outside, the puzzle has no up or down side. You can start the puzzle anywhere on any side, making it extra challenging.”
Uh, OK. Evidently there are a lot of really adventurous puzzle solvers out there, since the first run of the Infinite Galaxy Puzzle has sold out, ruling it out of any list of possible holiday gifts this year. But you can pre-order a copy at the Nervous System online store right here and get yours sometime early next year.
