How was it done?

BallParticle2 was done in Maxons Cinema 4D.
Here I used the BallParticle1 (take a look
in the .readme file of it for a description)
six times, every BallParticle1-system starts
its motion a bit later.



How long has it take to do it?

It has taken around 1 hours of animating
and about 1-2 hours to render.
