Sweet! I am so happy to be done w/ that ugly Windows Logo! If you are using "small icons" in your toolbar, then this isn't the right size and I can't see the hover animation. Any interest in releasing a smaller version? Or releasing it as a transparent PNG... and I will resize it myself?
I sort of got the animation to work. Open the file up in photoshop and copy the entire image. Then go to the channels tab (beside the layers tab) and paste into the alpha layer. Save it as a BMP and it should have the animation!
