silicon case for macbook pro

does anyone know who makes the silicon skins u can get for iphones/ipods but for a macbook pro. i want to get my gf one to go with her mac for xmas but cant find em :/
 
Ebay maybe?

I actually bought a cheap ass one off there (not silicon skin thing though). Cost me about £4 in total lol.
But then again, I didnt really need one, just wanted one to put in when its sat on my desk doing nothing (extra protection, y0!).
