Trying to dream up a story about some guy who's into self-restraint. I've spoken to such people and they're able to chain themselves up and a type of time-locking device frees them.
In my story, the guy's very clever indeed, inventing a futuristic machine which chains him whilst torturing and feeding him daily. Only trouble is it develops a fault and will never unlock. So, he's now condemned to a life sentence in this machine.
I'll have to dream a few techy details up, i.e. how does the machine get food, etc but that's no big deal.
Any ideas? Will it be as dull as dishwater?
