Boot animations are the logo, picture, or movie that plays as your Android phone boots up.

Here is a simple boot animation that I made for OmniRom. It has an old school 1985 feel to it.

It is 1080x1920 resolution.

Be sure to rename it bootanimation.zip and put it in /system/media in place of the original file. You can rename the original to bootanimation.bak, if you want to save it for later.
