Diffusion limited aggregation in ICE

Diffusion-limited aggregations are formed in nature as a result of particles of matter diffuse through a solution and are deposited onto surfaces over time, forming nodules or clumps. Examples are mineral deposits, depositions on electrodes during electroplating processes etc. It’s a relatively easy process to mimic in particle systems. I’ve created some ICE compounds which let me create aggregates with varying tropisims, deposition rates, separation and so on. Here are some results.
