Klein Bottles
Websurfing recently, probably via Anton Sherwood's Muttered the Ogre site, I came across this picture of a Klein bottle at the site http://www.kleinbottle.com/, which sells them at reasonable prices. A Klein bottle has no inside. Start on the outside and keep moving your pointer on the surface, and you can come right back the point at which you started, having covered every part of the bottle. A Klein bottle is the 3-D analog to the Moebius strip.
