Hey guys. I have had this bill warp sort of effect I have been doing for a while but before I show it to youtube, I want to be sure I have the right crediting for it. Can you guys tell me if this has been done before.

A bill is signed on the face and folded in half so the signiature is on the inside of the bill. A bulldog clip is introduced and you clip the open end of the bill together so it cannot get out unless you un-clip the clip you take the bill and either rotate it 90 degrees, turn it over, wave your hand etc. They VISUALLY see the bill turn inside out inside the bulldog clip without touching it and the signiature is showing on the bill now. Has this even been done? I have not seen many effects involving a bulldog clip.
