Thanks Acorn. I worked out the ball rotation on my own thanks and I've updated the demo.
I'll give the keyframes a go next
Update: Okay, I've added the keyframes and they work well cheers. I've only applied small amounts of Y axis movement, max 3 to -3.
What I like about this is that the whole thing is nearly all svg and the only two things that are bitmaps (tiny at that) are a feathered rectangle that gives the illusion of rotation and another white rectangle with a linear transparency.
UPDATED DEMO
