The page certainly doesn't have enough explanation on it - in particular, I've always intended to add more information about the sets of objects that can be selected and about how to program in new ones, and it's been useful to get feedback from you about this.

I suspected that you didn't get a lot of feedback from this particular simulation, so I decided to give you some even if didn't understand it. I didn't have time to restudy it yet, I'm studying the JavaScript from your simulation versions of my model. I found a way to reuse the bar sent by a particle at the moment it is hitting the other particle on your third version. Now, I'm trying to apply it to the last one. :0)

The pre-programmed objects all relate to discussions on this forum, so they were aimed at people who already understood things that the page itself doesn't explain.
