This is taken off NetLogo's Follower's simulation.

For the uninitiated, NetLogo is a software for creating agent-based models. The simulation you see is taken from one of its model.

Each agent starts with being RED, and search for someone to follow. The start of the line becomes YELLOW, and the last of the line becomes GREEN.

This process goes on, adding more to the line. The middle agents are in BLUE.

What will happen when this goes on and on? Comments below to make a guess.

Enjoy the therapeutic vibes from this simulation, while learning a bit about agent-based modelling!
