Virtual paint-a-room to visualize colors?
I vaguely recall a few years back that I read about a free service where you could upload a photo of your room, and actual humans somewhere would (invisibly) mark off paintable areas, and you could then try out what your room would look like with different color walls and trim. But now that I want to use this kind of tool, I can't find it. Maybe I was dreaming. Anyone aware of a good free tool like this?
