Okay next - adding the light... So these are quite beautiful... Its also very interesting that some researchers are focused in recreating caustics in the field of computer graphics.

A simple mouse made with fun fur and an empty film canister. I made this mouse for the May workshop here at the Science Museum. The mouse was pretty simple to construct -- just some fun fur, an empty film canister, and a gear connected right to the motor -- the hard part was making it move convincingly. I wanted it to twitch, but just using the MOTOR_ONFOR block turned the motor on for too long. So my friend Natalie suggested I try programming it using the text language. So I made two blocks.
