The main texture, is a render of the head in wireframe, with a flare in each eye socket. This is then mapped flat, with the Green NOR button pressed instead of the usual ORCO.
Looks very sweet ,
I dont know if it is possible , but if you can slowly rotate the mesh texture frame by frame for an animation you can come up with a wicked looking electric ball effect , somewhat close to this
Except with AVI and blender renders the effect would look 1000 times as cool
