Recently a friend of mine dropped up a pretty battered old Megadrive.(With a totally battered Bomberman cart sticking out the top) It's been sitting in a shed for over 10 years, so I'm not going to plug it in as it'll probably burn down the house.
After seeing someone make a guitar out of one, I wouldn't mind trying my hand at some similar oddness.I have a heap of multiple consoles, so they could be cannibalized for the cause.
So far all I can think of are;
Putting a snes/ps1 inside of it.
Use it as an external hard drive casing.
Hmmm. It would seem I have no imagination.
