This is my first success with the following new implementations:

* Goodbye Forward Euler! Now I'm using Heun's method (also known as Improved
Euler), it is a second-order explicit method, similar to Runge-Kutta, but RK
is of 4th order. It seems that I can now take much larger steps without
worrying too much. I'm still using a variable-timestep scheme.
* New damping process to avoid in-cloth oscillations.

You can see a higher quality DIVX video (1mb approx) in

I look forward to your comments and suggestions!!!

Fernando.

ps. I have to leave for 3 days, so I'll leave my computer crunching a much
more complex problem!
