We now have two video projectors installed in the space!  One of them beams across the room onto the "smoke turd" graffiti on the west wall, and I think we should consider painting a white rectangle there or perhaps hanging a white sheet over it, or perhaps in the middle of the room (although the image would end up larger and harder to see since it would be overhead)

The other projector (on top of the TV cart) beams at the south wall which could use a fresh coat of white eggshell paint to be a better projection surface.

Valerie says there is paint we can use downstairs, and if anyone knows how to use a roller and stick this could be an easy task
