Adjust "surface tension radius" (droplet attraction size), "max step" (distance dots move before dot randomly changes direction up to the adjustable "max turn"). Combines sticky dot action with droplet-like formation. Turn %surface to 0 for only sticky dot action, or 100% for full droplet causing surface tension.
Surface tension, which makes droplet clusters, competes with sticky dot aggregation and random motion, which makes tree fractals. Dots stick to previously stuck dots (diffusion-limited aggregation DLA). Viscous fingering has thicker tips than DLA due to surface tension. Scientists don't know how to simulate viscous fingering via competing DLA and surface tension, so I'm trying. Variation of my earlier Diffusion Limited Aggregation. Random sized dots start at random positions, move randomly, stick to stationary particles. Starts with one stationary "seed" dot. Moving dots (white) stop when touching colored (so no need to limit to only 1 moving dot at a time, as in the days when programs had any touching dots stop).
