Mandala Live Wallpaper is a live cellular automata which evolves all the time on your Android device.
This app started as a week end project, based on the work done by this guy.
The algorithm has been tweaked a little bit in order to add color shadings and turning it into an Android Live Wallpaper. You can download it for free from the App Store.
The source code is available for free to anyone on my GitHub, I hope it will be useful.
