Mobius Strip...

I came across the Mobius strip somehow. Its really cool. Do try the activity in the following link:

Also, see the Art and Popular Culture tab in its wikipedia entry ( http://en.wikipedia.org/wiki/M%C3%B6bius_strip )

I had no idea about the use of mathematical concepts so much in writing and other forms of expression.

And for no obvious reason I'm finding this very cool and am very happy about it :)
