Just read about this cool project by Koinup: 3D Wallpapers
Basically they're collecting the best images of virtual worlds and games and turning them in wallpapers for an upcoming mobile app that will be available on several mobile operators.
I think that the value of this initiative is that it brings contents, images, fanart inspired by virtual worlds and videogames to a new level. So, kudos to Koinup!
In order to pick the best images. Koinup launched a couple of contest, the first is for Second Life Snapshots, the other is for picking the best avatars.
