Hi!

I'm really unexperienced in physics programming and physics math, I don't
even understand most of the discussion on this mailing list, but a few
days ago I had an idea for a game, and quickly came to the conclusion that
a 2D physics engine will be the most beautyful addition to it. So I
checked a few introductory papers and coded most of it up in an afternoon.
With an amazing feeling of success and having lots of fun watching things
bounce around :)
Of course it's the above mentioned spring-mass-funny-integrator engine,
but I don't even have a clue of what makes a true rigid body simulation
superior. Maybe that there I can apply parameters to joints?
Anyway since I spend most of my time laughing at bouncing blobs of jelly,
at this point of development I'm satisfied :)

So why I wrote this mail was that I would be happy to hear more about the
difference between this simple engine and the true rigid body thing.

Cheers,

Daniel
