This still needs a bit of work on the handle, but most of it is there. Can
anyone guess what the molecule is? (it's kind of obvious ;-) )

Yep. It's based on a real mug I have - see

I recognized the molecule immediately, because I have a similar
mug...except mine is white ceramic and has "Caffeine©" under the
molecule.

Very nice model, and I like the stain on the cd... my only niggle
about the picture is the copious amount of blank space at the bottom
of the picture...

Thanks. The CD was simply done by putting it straight on the scanner,
ring-marks and all. I actually put my drinks on the freeserve CD most of the
time (best use for it).

I didn't really notice that when I was building the scene, since I usually
stopped the render half way through. Don't worry though, I do have plans to
put some more stuff in to fill the space - probably a few pages of
mathematics and a calculator.
Speaking of which, does anyone have a model of a Casio fx-9750? All of the
calculator models I remember seing were TIs.

Hey, no formal chem whatsoever! (Okay, two weeks of it, but basically so far
we've just relearned how to use a triple beam balance for the fourth year, gone
over metric conversions for the sixth, and been introduced to nomenclature of
compounds.)
Yeah, they make all kinds of stuff with caffeine.

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...

I quote from http://mathworld.wolfram.com/kleinbottle.html :
"A closed nonorientable surface of Euler characteristic 0 (Dodson and Parker
1997, p. 125) that has no inside or outside. It can be constructed by gluing
both pairs of opposite edges of a rectangle together giving one pair a
half-twist, but can be physically realized only in 4-D, since it must pass
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
through itself without the presence of a hole."
The model of the Klein bottle is an immersion of the 4D object in 3D space,
and has to intersect itself just as a 2D projection of a mobius strip has to
intersect itself. As such the 3D Klein bottle isn't a real Klein bottle any
more than a drawing of a mobius strip is a mobius strip.
The issue of volume is a somewhat misleading one, since AIUI topologists
usually deal with infinitely thin sheets and the volumes they enclose,
rather than with solid objects. A surface can be 2D but still require 3
dimensions to exist, as the mobius strip demonstrates, and similarly it can
require 4 dimensions to exist, as in the case of the Klein bottle. I could
be wrong though, I have no formal topological training.
