- Object shape (they don't have to be balls)
- Grid distance
- Distance between balls
- Lift speed (how fast do they "jump")
- Gravity (how fast do they fall)

- Ball size
- Lift neighbors (how many neighbor balls are affected when a ball starts to fly)
- Color of balls
- Random color changes when touched (on/off)
Playing around with these controls can make them change behaviour quite dramatically. From a slow jello to popping popcorns.
If color changes are enabled each swipe will generate a new random color and the balls you touch shift color. After that they "bleed" this color to their neigbors and after a while all colors start blending together to a nice smooth gradient. Your wallpaper never will look the same from one minute to another.
And please comments, bug reports, improvements, suggestions - just write them here in this blog.
Enjoy!
