So My sister is moving out, that means i get her room to use as like a game room or entertainment room, im going to paint designs on the wall, and so i need help with that so if anyone could give me some ideas, like maybe go on Microsoft paint or whatever, and just creat something, it would be great. (no black walls, parents wont approve of that)its going to be lime green so base it off of the colors of xbox. room size: 10.5' X 11'
