Tiling {p, q}
In the hyperbolic plane, a {p,q} tiling has p-gons meeting q at each vertex.
Condition: (p−2)(q−2) > 4 for hyperbolic geometry. Euclidean is = 4, spherical is < 4.
Color encodes depth (generation) from the central tile. The disk boundary is the "circle at infinity" — points at infinite hyperbolic distance.
All tiles are congruent in hyperbolic geometry despite appearing smaller near the boundary.
