Light Strips for Home Decoration?

Smegoid asks: " Three cheers for light strips for case mods and all that, but what about light strips for interior TRON style design? Wouldn't mind Tron'ing out my apartment. Anyone know a source for strips longer than 1.5m? What about powering the stuff without using a computer power supply. The potential for light strips goes well beyond a computer case. Think lightcycles, think MCP!" I wouldn't go as far as TRON but a room tricked out with a nice glow-light would make for a really cool effect. If case strip mods aren't an effective way to get this kind of look, is there another way to go? Long before I discovered light strips, I thought that fiber optics and some colorized light source might be the way to go, but what kind of light sources work best with fiber for best described as "mood lighting"?
