M.C. Escher and the Moebius Ring.

In the artist worksheet, one of the question asked was, "Is it possible to create a Moebius Strip?" I thought right off the bat that it was, but then I started questioning it more and more. So apon googling it, I found that it was possible...there's just a good amount of math involved.

I also found this which deals with the actual optical illusion aspect of the moebius ring. If you place an ant on one of these strips, it will have touched EVERY part of the strip before coming back to the starting point. You can see this in an animation on the webpage.
