Here we add the rule that an island can spend resources to create a boat. The resources spent are determined by the distance between the islands.
Rule 11: An island can create a boat and send it to any other island.
Rule 12: The greater the distance between islands the more resources needed to send a boat.
You can see the resources being used up as boats are sent from island to island. The visualization now represents something similar to synapses firing in the brain.
