"Bringing Vector Graphics..." does not "sparkle" in Safari (but does in Opera)
There is some sort of animation that he's using to "sparkle" certain characters. Sets of characters change from black to blue/grey over time. I'm not yet sure how it's being done, we'll need to make a reduction.

Reduced test case (showing our failed clippath animation)
SVGClipPathElement::childrenChanged should take care of the rect animation in the clipPath :-(
Fixed in trunk.
