Nice job on the simulation but I believe it would be more interesting and educational if you could provide some explanation as to what we are looking at. For example, what do the red, white, and blue dots signify. Also what is actually happening when those dots are moving in different directions. You can add those explanations directly in the scene (by editing it) or in the scene description.

This is only a suggestion. You make the call whether or not you want to make those changes.

Thanks!
