As a sophomore in college, I worked at Agora Games as a community manager for Tony Hawk’s American Sk8land.
The online community supported uploaded scores and artwork:
skate decks and graffiti tags drawn with the Nintendo DS.
I took all of the uploaded graffiti art, and used a GIMP plug-in to transform it into a giant mosaic of the Sk8land box art.
This was featured in Nintendo Power!
