Bowls made of confetti! Great recycling art project--save all those leftover paper scraps (put in small bowls at each table). Collect a bunch and have the kids cut them up; Then make bowls made from confetti.
I like the idea of framing the TV with wood planks. I think I might just put some planks directly on the wall and center the TV on it instead of doing floor to ceiling. NOW it just needs hanging accent lights mounted to the ceiling above the tv and DONE!
