I think I'd like something industrial/steampunk-ish like this. 6 of these along with a 6 canister track light on the ceiling. I just have to get them where that angle is variable because the wall they'd go on is slanted.
I also wat to have an electrician in to look at isolating the circuit where the computer is plugged in. It may already be. I don't know. That's not my area of expertise, but my friend Brian will know.
