Cool upgrade to the Artificial Chemistry!
Though for some reason i can't yet reproduce my favourite multi-layered aggregates (which are stable only because outer shells prevent incoming particles from interacting with the core layers),

Thanks for trying it out! In chemistry life every combination of particles had a different radius where they interacted, thats why you don't see those shells anymore. I'll add it as an option in the next version.
