Quick and dirty Python script to generate nyancat boot anmations for Android, designed with 1280×800 in mind.
This script generates a bootanimation.zip file which contains a seamlessly looping boot animation where a nyancat flies from beyond the left edge of the screen to center and stays there until device is booted.
This script depends on Pillow.
Image mockup via placeit:
Image is cropped to 800×800 by default for performance reasons. Looks like KitKat does not support background color setting.
Do understand what are you doing, don't do stuff just because internets told you so.
Root is needed.
copy resulting bootanimation.zip to /system/media and set it's permissions to -rw-r--r--.
