Well this is puzzling, I've extracted the code from the larger SVG document, I have a starburst pattern, that I'm trying to rotate on mouseover, but I can't get it to rotate in the simplest scenario.
Since the shard shapes of the Starburst exceed the SVG viewbox, which essentially masks it, I'm wondering if this overspill somehow disables it animating?
Secondly: The starburst pattern stretches across the full screen, so I've put the rotation axis as the center of the screen, but in reality this is wrong, the center of the starburst is significantly off center in the viewbox. I presume that SVG numerical values are all pixels? I can just get the pixel co-ordinates of the starburst origin and use that for my rotation point?

The most important change is using animateTransform instead of animate. Also since the group you want to transform already has a transform attribute, I've wrapped the group in another group and I'm rotating this one instead.
