Variations on the Theme of Life

I have always been fascinated by the emergent properties of mathematics: simple rules create complex structures. When you get down to it, this is how all of our modern technology works. Variations is based on that concept and was composed for performance through an application written for the iOS® operating system.
At the core of the application are cellular automata based on Conway’s Game of Life (1970), which is a grid where each square is either ‘on’ or ‘off’ and follows a strict set of rules. A square that is off (‘dead’) can become alive (be ‘born’) if it has the right number of living neighbors. A square that is alive can die if it has too few (loneliness) or too many (starvation) living neighbors. The rules are simple, yet they can create astonishingly complex patterns; there is an entire field of mathematics devoted to studying these patterns, Automata Theory.
Variations allows these patterns to play out both visually and aurally. Tap the screen to allow the grid to move through another cycle of living and dying, or just listen to the music created by a single frozen moment. No two people will ever hear the same set of sounds: the starting point for the patterns, as well as their evolution, are uniquely generated every time the Variations application is run.

(The recording above is from the premiere, in which the audience was asked to open the application simultaneously.)
