Build Your Own Hyperbolic Plane

The hyperbolic plane can be modeled in a variety of ways, each construction revealing different qualities of this surface. In the hyperbolic soccer ball model the (five sided) pentagons of the classic soccer ball are replaced by (seven sided) heptagons forcing the creation of a surface that curves out rather than in.

In the polyhedral annular model, thin strips are taped together, fanning out from a central point to reveal the exponential expansion of hyperbolic space.
