A big collection of plymouth themes, ported from android bootanimation from here.

Plymouth is a project from Fedora and now listed among the freedesktop.org's official resources providing a flicker-free graphical boot process. It relies on kernel mode setting (KMS) to set the native resolution of the display as early as possible, then provides an eye-candy splash screen leading all the way up to the login manager.

follow this archwiki article to setup plymouth in archlinux or any other distro.

Download : you can download individual themes via link below -

Clone : or you can clone this repository if you want -
