Particles wander randomly from the edge and stick where they touch the cluster. The result is a branching fractal — like frost, coral, and mineral dendrites.

Fractal dim.≈ 1.71

Governing equation

R \approx N^{1/ D_{f}} = 1^{1/1.71} \approx 1

Reading this result: Each walker sticks on first contact, so exposed tips capture particles before they reach the interior (screening) — that feedback is what makes the cluster branch as an open fractal.
