W.I.U.T.H.E.T.?
Foam fragments of the hyperbolic plane, formed from straight flat strips of foam. Differently spaced teeth on the sides of the strips force them to curve at a steady rate: any surface with equally spaced curves that are turning at a steady rate must have constant negative curvature. What is up with the Hilbert Embedding Theorem anyway?
