2D DLA Experiments

DLA is short for "diffusion limited aggegration"[0]. There are particles performing a random walk [1] and they aggregate (= stick together) if they come close enough to each other.

In the second experiment with directional bias the particles are experiencing a constant drift on top of the random walk (or are maybe having unequal probabilities of moving in different directions?)
