Recursion is a powerful software method as well as a generally powerful technique. It is feedback. Just like amplifier feedback, it can scale to a physical limit very quickly. In this case I am using textures to generate new textures. It happens very quickly and does create very complex and interesting images. The problem with feedback upon reality is that at some point reality itself becomes ambiguous.
It certainly gets to the heart of the matter very quickly, but finding a way back to the mundane, could be even more complex.
