For a brief moment while watching that I completely understood curvature of space, relativity, and quantum theory. Then I lost it, poof! What a post. Blowed my mind. thanks.

So can he show us what a Möbius transform looks like when applied to 3D objects? I'd like to see how a complex model looks as it's turned inside out.

Fantastic. For number theory fans, Mobius transformations are crucial to the theory of modular forms -- sort of a higher-dimensinal version of trigonometry in which the zoo of transformations of the plane depicted in this video replaces simple translations of the line.

I am currently studying for a PhD qualifying examination in analysis, the field where most students first encounter these types of Moebius transformations.
The animation was very pretty, and a good depiction of what's going on.

Only loosely related, but you can find a couple of classic math videos on Google now: Outside In (sphere eversions) and Not Knot (hyperbolic knot complements).
Then there's the Indra's Pearls book and this batch of Java visualizations (check out the punctured torus / Kleinian group limit set app).

Thanks, Wolfdog. Cheers, everybody; this is mainly down to me having such a shower of smart-arses on my f-list.

Ever since that Björk thread, every time I see an "o" with an umlaut over it, I see a little surprised face.

See?
It's probably good I'm not German.

Beautiful - thank you!
Would that this had existed when I was trying (and mostly failing) to learn such things.

That's so disgusting in so many ways that I feel like I need a shower.

Got that? There's going to be a pop quiz on this tomorrow, so pay attention.
Propers to tdj and his beautiful blog for the lesson.
