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.

Aha, got it now.

But all your messages with attachments have been cancelled, so I couldn't
see them.

Not at all - if there's any resemblance, it's a pure coincidence...

I came up with it this way:
I had implemented user defined gravity, and was considering possible demo
animation ideas. Gravity is space seemed like an obvious idea and in order
to make it more interesting I used two planets instead of one...

I considered making them bounce (high), but that would have been really
confusing.

I also considered making them bounce just a tiny amount, but that seemed to
cause unstable results, so I dropped that idea...

No, but it's closer to the camera. :)

BTW, you don't need to quote my entire message (including my sig even!), and
especially not *below* your own reply... Just quote the part that you're
actually replying to, or if you're replying to the whole message in general
you can leave out the quote entirely. And then place your own reply below
the quote, as if it is a conversation (which it is!).
