If you want some awesome Spaceship Earth wallpaper for your phone, check out Wallaroo from the nice folks at Iconfactory
oh, man I had forgotten about the Iconfactory. These folks made customizing the look of my old mac pro back in 2004/5 such a delight. Thanks for reminding me about them!
and it looks like they've got some wallpaper out there from Louie Mantia - cool stuff!
