The infinity puzzles are a new type of jigsaw puzzle inspired by topological spaces that continuously tile. Because of that, they have no fixed shape, no starting point, and no edges.
The intricate branching shapes of our puzzle pieces emerge from a simulation of crystal growth and are lasercut from plywood. [...] Instead of mapping to a torus, this puzzle maps to a Klein bottle, an impossible 3D shape where the inside and outside are mathematically indistinguishable. This means that the puzzle tiles with a flip. Pieces from the right side attach to the left side but only after they have been flipped 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. This puzzle is adorned with a photograph of the galactic center from the Hubble observatory. The image is continuous from one side of the puzzle to the other, so it's not possible to see the entire image at once. Explore the galaxy while assembling the puzzle in multiple ways.
