I just put a spin on the coin by duplicating it and adding some transparencies...
I also motion-blurred 2 coin layers to enhance the spinning effect.
I used a black brush and gaussian blur to create a shadow for the coin and that's it.
I'm just kidding, the coin is really spinning on fluffy's nose ;)

Well this theme looks easy, but is hard to do...

Anyway I tried making an biker who was doing an 180 spin in the air as a mime...

My shadowing maybe little off here, since I based the shadows here as per the biker light source and not the stage lights...
