This is to announce that **orx-force-2d** demos have now descriptions. You can read them and see screenshots at

I had fun running them and understanding how the programs work to write those descriptions. I noticed that one can get wildly different behaviors by making small changes to the simulation parameters, even without any change to the logic. I think one could spend a whole year experimenting with this orx and getting fascinating results.

Feel free to share any experiments you create, or feedback on those descriptions.
