He's build some sort of binary adding machine that plays sounds based on the current number, which adds to the total every clock cycle. IT creates patterns based on the total not including overflow. The use rprovides a 3 bit word to the counter. Te counter outputs a serial transmission to a decoder. Both of these things are connected to an Ardunio, which is connected to SuperCollider. The counter outputs 3 bits to the ardunio. the decode does one bit?
