In this geometry, distance is measured like a taxi driving along city blocks instead of a straight line. That means “circles” look like tilted squares.

Patterns that fill an infinite curved space where tiles shrink forever at the edges. Made famous by M.C. Escher’s Circle Limit.

A tiling discovered in the 1970s using just two shapes that never repeats, yet still looks symmetric and beautiful.

A bottle with no inside or outside — like a Möbius strip taken into 3D. It can’t truly exist without intersecting itself.

Pack circles inside circles forever, and you get an infinite fractal pattern with no gaps.
