I'm convinced that there's something interesting I can do with paint on this blank wall before remounting the 60" plasma you see on the floor and the 3 on-wall speakers you see around it. All of these items are high-gloss black. I've tried a few things, including painting this whole wall, but none have worked out (which would be why you see that big bucket of paint next to the tv)...

Now I'm thinking about painting some kind of frame or box behind everything (like the red outline I drew on top of pic) but have no idea what color, light or darker, matte or glossy, etc would look good as a background for the gloss black plasma and speakers, assuming this idea is even a good one. None of my previous ideas turned out any good, that's for sure.
Doing a little subtle decorative work to offset the behemoth you're about to put on the wall is a great idea. We go with a tone that is not a mid-tone - something between the dark of the TV and the light of the wall.
As far as what color you choose, we'd go with a warm color (red seems very nice to us right now - but brown would be a more discreet choice. We'd also head over to this post at ATSanFran to see how a few folks used artwork to offset their flat screen.
We'd also head over to our Home Tech site and look at these posts: Small Cool Tech Setups 2007. There are a good many variations on your theme here.
