This short movie shows a diffusion limited aggregation process without driving forces. The particles move on a 50*50 square lattice: they are injected from the boundary and perform a random walk until they touch the growing structure. If you want to know more look into any good book on fractals. A specialized reference is Witten & Sander: "Diffusion limited aggregation, a kinetic critical phenomenon", Phys. Rev. Lett. 47 (1981) 1400. Enjoy.
