Ice Cream Sandwich 3D. All Android fans will love this wallpaper. It depicts an Android-shaped ice cream sandwich which gets eaten accordingly to battery level.
You can customise colours of both background and ice cream, and disable battery indication if you don't want to see only bottom part of Android left on your home screen.
Full version has two models of ice cream - Android and a long bar. Also it has additional colours and even crazier shapes of background than in free version.
