The building blocks for the renders are a simple rectangle and a circle. Each permutation returns a random ratio (within a threshold) and a random rotation angle. Then both shapes are taken through a loop which determines the current number of iterations and hence complexity. Look next to the visualization for its composite shapes, rotation angle, iterations and a record of the previous render.
