I've always wanted an overhead projector, and now I -really- do. I could probably even do something cool in my house with a regular slide projector. Both are pretty cheap on eBay and would be useful in my future teaching career. I think kids like it when it's dark in the room and there is something bright for them to look at. I mean, that's what we do in theaters and when we watch movies, so what's up with all the bright overhead lights that just make every little distracting thing visible in the classroom? Is there a theory behind that, or is it just cheap and generic?

Anyway, the reason I want a slide projector right now is that I came across this website and then I found this installation by Kara Walker. How cool would something like this look in my living room?
