Laptop skin web sites are a dime a dozen. Infectious is different because, as far as we can tell, their laptop skin illustrations are voted on by a community of talented illustrators. You won't get lame stockphotography-for-skins here. Some of our favorites from the bunch include:

A very long journey by zutto (pictured above)
Mysterious Forest by Simon Kim
The High Seas by James Hancock
Speakercloud by Zeptonn

I should probably also mention that Infectious also has car decals, iPod/iPhone skins, and vinyl wall art as well.
