I did this for my friend   houndgrey a while ago and promptly forgot about uploading it.

Anyways, the story behind the GIF (and I pronounce it with the hard g thank you very much. If ya pronounce it with the j you better be talking about peanut butter)

When hound changed his avatar on FA to the current 8-bit one I decided to maybe try something with it if I could. I recalled Tecmo Pro Wrestling for the NES and the fact it had training mini games in it. Suprise suprise when I over laid the avatar image over the stuff it worked out perfectly and I set to work making an image. But why stop there when I could just make an animation of it and do that. So I did.
