I don't get it.
it's not animated
You need an APNG plugin for your browser (which doesn't come in some by default). If you do have it, you might have to click the image once to get full size.
But that's why I also provided the gif versions since I know this is not universal.
SMIL+Apache Batik would suit you better than manually keyframing. For one, it'd be smoother, and two, it would work in browsers
I know there's cleaner ways of animating this (like if I had access to Flash), though for purposes for the Vector Club, I do need the APNG version so there's going to be a bit of clunkiness.
