I have the script for an animation of this chemical (and others for
EtOH and nicotine).  I'll render and post them sometime.

Here ya go....need to fill with liquid though, so that you can see
that it is all one surface.

I work in a computer repair place, and we used to have a lot more problems
with freeserve screwing up machines - it's the most popular free ISP here in
the UK (no idea why). Actually, I've only got 2 AOL CDs in my collection,
compared to 8 compuserves and 3 freeserves.

Oldstench is confused...I modeled the mug just as it was shown on the
web-site, didn't know I was supposed to be modeling a 4th dimensional
object.

AIUI, a Klein bottle is a 4 dimensional object. What they have on that site
is a 3-dimesional projection of a Klein bottle (Think of trying to draw a
mobius strip on 2D paper). It's as close as you can get in a 3D world, and
it is still a damn fine mug.

	Not at all, a Klein bottle can exist in 3D space (as the mig
demonstrates). What is impossible is to have a Klein bottle that doesn't
cross itself in 3D space, you need at least 4D for that. As for drawing
a moebius strip on 2D paper, you can't because a moebius strip is a
surface (eg it has 2 dimensions) but the klein bottle is also a surface
and not a volume, that's where your analogy fails...

For a moment this had me very excited and/or confused. I feel it reflects
badly on me that for a moment I genuinly considered the notion that
jet-fighters might well implement Klein bottles and similiar topology in
their design...

	Ooops, sorry! Here's what happens when you type too fast ;-))
