I like the idea but not his blue color and his bland appearance...
Here is my humble interpretation, always declined in black or white.
I changed too boot sound (more discreet than Sony one).
For eXistenZ roms, special bootanimations are here!

Simply flash chosen zip with recovery you want (all tested)
To come back to default bootanimation, simply delete "bootanimation.zip" located in data / local with a root explorer.
