Android comes with a pretty great set of live wallpapers built in -- and some manufacturers add their own, too -- but if you're ready for a change of pace, the UI nerds (we mean that in the best way possible) over at TAT have just dropped three of 'em for free. Called Artemia, Blue Range, and Retro Pixels, the trio run the gamut from dreamy aquascape to eBoy-esque 3D environment to 8-bit gaming, and they're all interactive in one way or another -- poking and shaking both seem to have interesting effects. They're in the Market now, so you may as well grab if you've got a compatible phone. Follow the break for TAT's movie trailer teaser video.
