Have you ever done a puzzle that has no beginning or end? Where you don't know up from down? Get lost in the Infinite Galaxy Puzzle.
The Infinity Puzzle is a new type of jigsaw puzzle that tiles continuously. It has no fixed shape, no starting point, and no edges. It can be assembled in thousands of different ways.
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. This puzzle is adorned with a photograph of the galactic center of the Milky Way. The image is continuous from one side of the surface to the other, so one cannot see the entire photo at once. Explore the galaxy while assembling the puzzle in multiple ways. The puzzle also features special space themed whimsy pieces.
