I think this was someones signature here.  I thought it looked cool and saved it to my hard drive.  Well, I wanted to find some similar ones on the net, but I couldn't remember the name of the user who had this as their signature. (I'm not even sure if this was the forum I found it on in the first place.)  I assume they're game sprites but it might be some well done pixel art.  I dunno.  If anyone knows what game this is from, the name of the creator, the person who had this as their signature, or the source of this gif, please let me know.  Any info helps!
