Some guy did the most metal thing I've ever seen so far. A guy called Prince Midnight decided his late uncle should get to shred for all eternity. His uncle Filip died in the late 90's in Greece.  He donated his skeleton to the local college and was medically prepared for the school.  After some years he ended up in a cemetery, and his family was paying rent on Greece they have a wierd situation with burials and cemeteries... Anyway, Prince decided that's just not how he wanted his uncle to spend forever. Instead he figured out a way to turn him into a guitar dubbed the "Filip Skelecaster".  You can hear Prince Midnight shred a cover of Darkthrone's 1994's Black Metal classic, Transilvanian Hunger.
