Since it will be hanging on a wall, make something that is a show stopper; like Hollow Cubes. That is really easy if you make half blocks and sew the half blocks into rows, then sew the rows of half blocks together. Look in Pictures and find Cat-on-a-mac's sticky. Look under Tumbling Blocks for a picture of that. It uses triangles in all the centers.
Other optical illusions can be fun, too.
