Andy Furnas: Mixture between perspective and simple goemetric shapes

This image shows how if you have a vanishing circle, instead of vanishing points you can think about a curved space, called hyperbolic space. In this perspective things looked warped, but in fact, all of the triangles in this image are THE SAME! i.e. with the same area and angles!! I know it seems crazy, but it's true. This also shows how using simple geometric objects, like triangles something totally crazy and cool looking can be seen!
