This is a demo of a Peggy 2.0 based giant LED system, which can be used to play old-school video games, or make generative music!

Details below.

via SenorBon:

We built a giant LED board, about 6.5×6.5 feet, with 900 LEDs using ping-pong balls as diffusers.

It can play Conway’s Game of Life, Pong, and Sketch mode that allows you to create a starting pattern for Life. We output board state information to a MIDI board that allows us to make music based on what is displayed. This gets interesting with Life, creating minimalist generative music.

See pictures here.

Thanks to Evil Mad Scientists for their Peggy 2.0, upon which we based the circuit for our project.
