DLA is a simulated growth process.

A particle sticky seed exists in a two dimensional field. Wandering particles are generated along the edges of the field. Particles stick to the seed to form a cluster. Every time a particle bumps into the cluster, it sticks and stays put.

The resulting pattern is a typical fractal object, looking much like something in the deep sea. An interesting phenomena is the consistent creation of tremendous empty spaces, often in the form of long channels or 'fnords'.

Press the REGENERATE button to start with a fresh, new seed object.

This simulation is called diffusion-limited aggregation. It is an effective, although slow, growth model for natural systems such as the deposition of metals during an electrochemical reaction.
