Image (1280x1024) and animation was taken from "Init Black Theme" splash theme (by ZaZo0o). Starting animation deleted and only logo loop stays, Source code was cleaned-up by hands.
On my Athlon64 X2 4200+ animation takes 5% (in average) of CPUs.
Maybe it can be reduced by making logo static and changing only sun-effect in loop...
