***** WARNING *****

This script is just a fun thing I wrote
after changing my own plymouth theme.
Read through it first to make sure you
understand what it will be doing. It
requires root privileges via sudo. It
comes with ABSOLUTELY ZERO SUPPORT from
me. I have only tested it with PNG images
with transparency and dimensions of roughly
250x250px.Feel free to modify it to suit
your needs.
