I was looking at theremins on ebay and found this terrifying one made out of baby boll's head with glowing satanic eyes!
If that doesn't give you guys Norwegian wood, I don't know this cantankerous, weirdo audience. Even better, it appears the seller has made several different ones, all in the $75 range, so if you want to wave your hands around a baby's head to coax out strange whines you can do it far more cheaply than possible with a real baby. (At least when you factor in blood stain removal, prison time, etc.)
I'm calling it: Borg baby head theremin is totally the hot indie rock trend of '08.
