Hi Dan, The rotations are actually far simpler than they appear. All is does is perform three rotations about three orthogonal axes (think roll/pitch/yaw). Believe it or not, the rates for the three rotations are constant (though they do differ from one another). The apparent speeding up and slowing down is due to the different rotations sometimes reinforcing each other and sometimes cancelling each other. Tom Dan Asimov writes:
Really, really, nice!
Question: What is the rotation sequence used?

Hi folks,
I've put together a simple interactive polyhedron viewer which might be of interest. It requires a web browser that's current enough to support html5, and JavaScript has to be enabled, but that's pretty much it.
Here's the URL:

You can click-and-drag the individual polyhedra to rotate them, or you can make them spin around automatically.
Some filters are available at the top, based on classification and on rotational symmetry. Please note that the rotational symmetry designations are deliberately broad and imprecise, so please don't flame me for their lack of specificity; it's intentional.
I should add that the click-and-drag functionality won't work with a touch screen, so you'll want to use a real mouse to use the full interface.
Anyway, let me know what you think.
Tom
