This here is the first animated example of the Bleeble python AddOn for Blender 2.6.1, currently in development.
Bleeble is a new Blender AddOn for version 2.6.1 or better. The concept behind Bleeble is that you create selection sets and animate parameters for those sets. In this video the two sets are represented by the two colors. Using a 12×12 torus as a source mesh, two sets are mapped to two different code types or generation algorithms. Each code type has its own color or material. The orange set is derived from the center ring of the torus. It uses code type 2 which generates recursive protrusions or inset. The red set generates from a different face selection set. It uses code type 1 to generate random size protrusions whose seed changes over time.
