“Hyperbolic” Polysphericons
“Hyperbolic” polysphericons differ from the common polysphericons with respect to the curvature of their surfaces. The concept of curvature is therefore …

Polycons
Polycons have been devised by David Hirsch who patented the sphericon after having discoverd it (independently from others) in 1980. In comparison …
