Thats cool. I been messing with it. some may say its allot of work to unwrap the mesh like this, but i'm finding so far its easier then grabbing faces and jockying them around, also reduces the chances of a seam between faces where a multi grab of one area ( like the head) creates several possible seams that are a pain to fix. ( where 2 faces meet but you got them on 2 seperate grabs can sometimes make a seam you can't fix unless you redo your grab. especialy it seems the closer you get to the tolorance limit for the facing of the grab. )

hehe I hope that makes some sense. :P
