It is a strip or band with only one side. You can easily make one yourself with a piece of paper and some tape.

The Wikipedia article on the mobius strip

Take a strip of paper, say an inch wide and 11 inches long (specific length and width are really unimportant) and some glue. The paper has two sides, right? A top side and a bottom side. Now give the paper a half twist (so what was the bottom side of one end is now the top side). Glue the two ends together. Now the paper has only one side. Take a pencil and draw a line down the middle of the band. You'll come back to your starting point andthe line will be down the middle the whole way around. Where did the other side go?

Yup. The scholarly discipline which deals with these subjects is topology. Topology is the only branch of mathematics which uses no numbers.

Not necessarily true--geometry isn't numerical, nor are many forms of astract algebra (boolian immediately springs to mind), string and game theory. Mathematics seems to be a study of patterns. Numbers (counting, integers, rational, real, and imaginary) are only a small part of the generality that composes the study of the math.

BTW a mobius strip is a two dimensional singularity in three dimensional space. It was exploited in the 60's in four and eight track tapes (the acid helped) and (Felix) http://www.kleinbottle.com/klein_bottle_hats.htm Klein bottles make great hats .
