The Biobolt is a disgusting tool, used to help "vegetables walk". Oh, I forgot to mention, it can also help people walk against their will. You might not find much about it, but it was developed at the University of Michigan. It is composed of nanoscale technology, and ASIC set, and it *thunk* fits on your skull, hidden by a flap of skin, easily showed back together with minimal scarring.
Oh, it's real. I remember when they had it. A nurse can buy the darn thing. Yuck.
