The materials and design (search “tetris solved” in Google images for a design pattern) are somewhat flexible. The idea is to create many different 1" cubes and piece them together in the form of the Tetris pieces. The Tetris pieces are then assembled on a board, creating a positive for liquid silicone to be poured on.

Cool down after your next marathon Tetris match with some Tetris-shaped ice cubes. The School of Engineering senior Billy Gordon created this project.
