Just released a new Android live wallpaper called "Bouncing Heart", since, well, it's got a heart that bounces. Very Valentine's day, no?
It's all one big fragment shader, ready to turn your phone into a wonderland of shiny pink hearts, etc. Give it a try, maybe it'll cheer you up. It's free!
If you've got the pro version of the Opus Live Wallpaper Pack, the Bouncing Heart is one of the wallpapers included in the pack. You totally want to buy it because it's awesome!
