I'm going to put a light (must be really bright) beneath my conveyour belt (it was supposed to be the images roll). When the user spin the handle the paper strip roll over and change the colour as well as the texture, so the light comes out with different shapes and different colours. Even I will try the different shapes onto my box, I think of the cone, the sphere, or a cut-off cylinder. I had a plan to go around and find some plastic papers, carton, lights, wires etc. but still not have an idea how I am going to arrange all of them into a box.
