For a minute, I thought I remembered designing one about 20-odd years ago when I was but a young'un. Thinking about it, though, I'm pretty sure I recall it was a domestic cooker. Heh. I like it. What sort of size do you have in mind? Since it'll basically be a box, it shouldn't be too tricky to work out a TF scheme. Maybe you could use G1 Viewfinder as reference...
Haha! Awesome! Will this come with working components, so it could stand up and still have the spin cycle going on in his belly.... maybe throw a cat in there or something?
