Sample project for a Live Wallpaper, heavily inspired by the Matrix animation (Matrix movie)
I tried to keep a minimum set of files and as few dependencies as possible. It will take some time / downloading on first start.
The animation / drawing code is "isolated" in the class
app\src\main\java\net\ctstudio\matritsa\DrawLWP.java
By starting with this class and leaving all else as is, you should have a good starting point.
The project does not handle different display densities or sizes, meaning it may look weird on very high/low densities or tablets, ...
Also does not have code for handling configuration.
