I lowered the elasticity of the balls and increased their number.
I'm thinking about using a blob (and much more particles) next time, but you
can bet it will be very slow.

Comments, criticisms, suggestions?

The realism of the simulation is outstanding!

But it looks unnatural to have the balls emitted from a single point. Try to
emit them from an area instead and then let them fall down more straight
(initials directions should have less randomness).

Keep up the good work! :)

These animations look great JRG. Maybe you could try varying the colour of the
balls as they drop, to form coloured layers as the container fills up. Was there
a reason you didn't fill the container? Does the render time balloon as more
particles are checked for collisions?

You're right. Maybe if the balls were shot by a cannon of some sort?...

Oh, thank you.

The animation would have been far too big to be posted here... but yes,
parsing time increases drastically as the number of particles grows :( The
last frames took about 9-10 seconds to parse (and a few seconds to trace),
but if more balls were involved I bet that time would grow more than
exponentially!

I love this animation!  I agree with Rune; the realism is just outstanding.
Great job, JRG.
