In Cellular, there is a grid of cells called the "Universe". Each cell can be either alive or dead, and their states change over

generations. There are rules governing how dead cells can come to life in the next generation and how live cells can either

survive or die. This is how life evolves in the Universe. You can group cells into a commune and measure the population

density of that commune. The population density determines the strength of the modulation signal, which you can use to

control the synthesizer parameters.
