A free program for Android, by Nicolas Faralli.
This free program lets you move 50,000 particles that are drawn to up to 5 places around the screen. The settings menu contains most of the parameters that can be changed you can tap on the top right corner to display the rotating gear, then tap on it to display the settings menu. Particle Flow also functions as a dynamic wallpaper. This will give a bright and exciting color to your phone as all themes are very vibrant.
The project at https://code.google.com/p/renderscript-examples/wiki/Gravity served as an inspiration to create this app. This is also free of charge so try it now!
