Physics-based balls rolling around your screen as a live wallpaper!
Balls rolling around your phone as a live wallpaper! They follow your finger, get pushed around by swiping, and fall according to gravity (tilt your phone).
You can change the colors of the balls (including random), change the force of gravity and touch, scale the size of the balls, and more!
Plus, it's tiny and efficient. It shouldn't take up much of your phone's resources, and definitely won't take up much of its memory.
If you get the full version (https://market.android.com/details?id=com.knflrpn.LiveBallsFull), you get even more options, including the ability to set your own background image. It also has an icon to place on your homescreen to quickly access the settings.
This is version 4. Please give feedback on functionality and desired features!
