The 'Shop Contest we run on weekends is for bragging rights only. deviantART don't fuck around, however. It's offering a $10,000 cash prize to whomever sends in the best wallpaper in a promotional Gears of War 3 contest offering a lot of other loot to the runners-up, too.
For the first time, deviantART is permitting collaborative entries, too, so if you and a buddy can activate Wonder Twin powers, you'll divide a prize package including $10,000 cash money, a Gears of War 3 limited edition console bundle not unlike the one recently unboxed by Ice-T, a one-year premium membership to deviantART and other fun stuff. Or go stag and claim it all for yourself.
