We enjoy how a simple rule can evolve into more complex results. We drew a bar, and then started with the following rule:
1. When a bar hits the bottom of the screen it makes a sound.
2. If the bar returns to its origin it also makes a sound, but a different sound (goldenratio).
3. Like a piano, the position in which a bar hits detonates a different frequency.
4. The top bar is inverted, and its scaled too according to the golden ratio.
We were fascinated how for some moments all the bars reached some kind of harmonic rhythm, only to be lost a few seconds after that point. Just like nature.
