Editing Diffusion-limited aggregation (section)

===Factors<!--Variables-->===
The resulting tree can have many different shapes, depending on principally three factors:

* the seed position
* the initial particle position (anywhere on the screen, from a circle surrounding the seed, from the top of the screen, etc.)
* the moving algorithm (usually random, but for example a particle can be deleted if it goes too far from the seed, etc.)

Particle color can change between iterations, giving interesting effects.

At the time of their popularity (helped by a ''[[Scientific American]]'' article in the Computer Recreations section, December 1988), a common computer took hours, and even days, to generate a small tree. Today's computers can generate trees with tens of thousands of particles in minutes or seconds.

These trees can also be grown easily in an electrodeposition cell, and are the direct result of diffusion-limited aggregation.
