I designed a werewolf head and made 12 different color versions, which can all be purchased as stickers or shirts on redbubble: http://www.redbubble.com/people/vanweasel/collections/219619-colorful-werewolves

You can also buy them as a collage like in the submission: http://www.redbubble.com/people/vanweasel/works/10515178-colorful-werewolves-collage

I figured people might appreciate having lots of colors to choose from if they want a shirt :o
