I like the idea of procedurally generated content. That is, media created through systematic process, incorporating randomization at some level, to result in an infinite array of possibilities. Replay value. Also, the way nature works.
Every tree, every fingerprint, every neuron, the outcome of a procedural process initiated by our DNA. Much of what we are, the branches that develop one way or another, depending on the precise chemistry that seeds that process.
