this may be the special case that buggers the theory, but in general, 3 axes
of rotations bad, 2 good, local rotations Baaaaaadddd.

Maybe!
Anyway, off the top of my head because I can't get to XSI at the moment, you
need to parent each cube under 3 nulls, each for x,y and z. Then when you do
your turns, you need to select the correct null on each of the 9 little
cubes you're rotating.
Something like that.

It wasn't a gimbling, 3 axis, local rotation thing, was it Chris?

Well, I had to animate one of these things recently and it is a nightmare.
You do a couple of turns and all works fine. Then you set-up the third turn
and key it, still it all looks fine. But when you play it back, everything
goes pair shaped in a big way. The rotations get all buggered-up and it's a
real head-blower to figure out.
In the end I managed to get about 5 or 6 turns completed. I'll dig out the
scene and re-cap on how it was parented.

have you opened up a Rubik's cube to see how it works? It's quite elegant
and you should be able to make it work in Xsi, after all, there's nothing in
there that attaches and detaches cubes to and from each other.

Subject: Rubik's Cube
I'm trying to think of a good way to animate a Rubik's cube. The most
obvious way that I can think of is to manually turn off and on a bunch of
constraints to nulls. Has anyone come across this before? Any tips or
suggestions?
Thanks.
