Ok... now I'm embarrased :)

Looks like I didnt scroll down enough to notice there was an soundtrack. :)

I'lll to try and do some math or something... if you watch the video and notice all the cubes Pulse.  But if I do a preview of the animation, because the entire thing build of a single cube replicated, all I see is a giant wireframe of cubes rotating, nothing like what the end result looks like, so visually I wont be able to time it.
