Intelligent MIDI Sequencing with Hamster Control. What do you think?

A full report and an example of the resulting music can be found here.

According to inventor Levy Lorenzo: "3 simultaneous voices were produced spanning 3 octaves and 3 rhythmic tiers. Each voice was controlled by two hamsters: one that was responsible for adjusting the rhythmic qualities of the melody and another that modified the note sequence. With all of these elements in combination, an output was produced with very musical qualities."
