I'm not sure. Check this one:

This is one of the first animations I made using springs. Maybe it's
accidental, or maybe it's because it is very simple, but it looks quite OK
to me, and it is almost totally rigid. I used euler too, and maybe 20
steps/frame.

BTW, I'm glad you are making this patch, I'm just sorry it's not ME who is
doing it. :) I would be probably doing something similat if I wasn't so
lazy to learn C some more. :) Oh, did I mention the anim is amazing? Will
the source be available?
