Mobius strip?

I thought it was just a piece of 10-key calculator tape with some kind of half-twist and then taped for good measure.

Whats the big deal? Even if it wasnt twisted, it would still be one continuous surface, wouldnt it?

no... it would have two continuous surfaces... that's the whole thing about the mobius stripe... it only has one side. look at it carefully or better yet, make one at home. not too hard.

I am a total math jock (re: can't do sh1t).

That just means that if you put your finger on one side and trace around the entire strip without lifting your finger up, you will have touched every side of the paper.

Somehow, strangely, when I first saw that pic, I immediately thought "floppy cable."

Yeah, that was pretty funny.

And every portrait includes the following exclusive features:

A built in shiny strip of aluminum foil, microprinted with the mysterious message "10DM"
Autographed by a real German Bureaucrat!
Engraved with cryptic messages like "Zehn Deutsche Mark"!
No two are identical - each portrait is individualized with a special serial number, printed twice for absolute redundancy!
Microscopically printed with the word "zehn", repeated over and over!
At least four copies of the number 10. This number is especially useful to students of mathematics.
Special artwork which is visible with an ultraviolet lamp.
Engraved with the years of Gauss's birth and death, as verified by a Major Western Government.
Pocketsized and perfectly portable - easy to carry to math class.
Non-magnetic, so it won't disturb your pocket compass. Conforms with Gauss's Law!

Its a 2D surface that forms a 3d shape. Of course I could be wrong.
