Thanks, that looks pretty cool actually.

I clicked on the first one and most of the animation is distracting and superfluous, like bars of a bar graph repeatedly bouncing off each other.

Does that sort of animation really promote learning? How much ornamental dressing is needed to keep visual attention but not distract?

Aren't they meant to be solid masses with particular collision properties? In which case showing how they collide seems to me exactly want you'd want to show.

EDIT - I just watched it with sound. I suspect you didn't and misunderstood the subject matter.
