The Random Clock is a short experiment that combines a sequence of random notes with a random colored pattern that moves clockwise. The notes are “arranged” in two “voices” and, at the beginning, their pitches and the intervals between them are completely random. As times passes, the notes “converge” to the single note E2 and also the tempo “converges” to ~120 bpm. When each note is played, a random box is drawed on the screen; its distance form the centre is proportional to the pitch and the angle increases at a constant speed.

The notes are played using a basic synth built in Reaktor Blocks (by Native Instruments), essentially they are sine waves.

This is the final video:

If you’re interested in the source code (Processing 3), let me know.

More ideas: try to mimic a real clock with the two clock hands rotating at different speeds; the speed and length of the clock hands should be initially random, then they should stabilize to a fixed speed and lenght towards the end.
