This is a really cool way to customize your phone by replacing the stock animation with an even cooler one.

Now then, if you're a PSP theme designer, the method of designing one is very similar to making a wave. Using ADB, the terminal emulator, or a root file explorer, you'll find a file named bootanimation.zip in /data/local. Inside it are two folders containing JPGs or PNGs (depending on the phone). These images are used for the animation. The file "desc.txt" contains dimension information. If you want to create your own, I imagine the easiest way would be to make an animation then export the frames as JPGs or PNGs.

-Installing an animation

Note: Make a nandroid backup before doing this just in case you screw it up.

This is a bit simpler than making your own. Just place the ZIP containing the folders part0 and part1 and desc.txt to the root of your SD.
