Yes, but this is one special case, in a 3 body system there are various
situations that can lead to a collision.

Sigh. If only all pov particle systems could do this, the world(s) would be a
better place... Reminds me of a program I had years ago that would simulate a
comet passing by the sun.

Back when I was going through university for engineering, we had to write a
program for a calculus course that calculated the movement of one planet
around another using some sort of series (I can't quite remember). I
thought I was pretty slick writing one in VB with a nice GUI, graphics and
laser printouts, I should've done it in POV.

Actually I feel/felt the same way, but I had to end the animation at some
point...

I love the way they just 'stick' :)

Scientific American? A few months ago there was an artivle about
a solved n-body problem. Rune's bodies start in the way that could
be stable but soon it drifts off.
