This time it's login screen stuff. Installed with Visage or your alteration program of choice (or the long way found on www.resexcellence.com), this replaces the Apple logo on the login screen with the alchemist's serpent cross, and the "Mac OS X" text with "Full Metal Mac".
Enjoy you guys! ^_^
(I might be trying my hand at icons next, if I can ever figure out how to make them...)
