Fascinating things Klein bottles. I bought one, at least a three dimensional representation of one, from a chap who makes them in the USA.

It's the 3D version of a Möbius strip.

One of the problems that topologists have is not being able to distinguish the difference between a cup of tea and a ring doughnut.
