I need to find a simple black/white design for a full wall. I'm thinking about having it cut out of vinyl and just stick it to the wall, unless I can borrow a projector and paint it. My roommate did a flower piece on two of the walls in the living room that turned out pretty well, but he just did a small 4ft flower. I want something thats 10-12ft wide x 6-8ft tall. Graffiti, Line Art, Pixel Art, Rasterized Images... I just need some cool ideas. Please halp.
