Dr. Robert Lang, creator of delightful Origami insects and several Origami books & CD's (including Origami Design Secrets) has made an Origami Klein Bottle!

Robert Lang's Origami Klein Bottle

From a single sheet of paper with no cuts, Dr. Lang made this fully interlocking Klein Bottle. It's a gem!

Like Robert Lang's insects, this is a nontrivial folding. But yes, you can fold this yourself... See Robert Lang's folding instructions for the Origami Klein bottle! .
