The 8th grade students started a unit on color theory by creating a 4" square design with a 1/4" border. The designs were copied x 8 then painted to show complimentary, analagous, warm, cool, black white, etc... Then they took their design on a double slab of clay and cut out their design on one slab and attached it to the other slab to create the raised tile. I wish I had a close up of the tiles to show the dimension. The tiles were arranged and mounted to wood and hang in the office. One of my favorite all time projects!
