Thank you very much!!!!

You're absolutely right: the model itself is a bunch of interconnected
springs. I try to make the springs as stiff as possible in order to make it
as cloth-like as I can, but too much stiffness need much more slow
computations and can lead into stability problems. That is specially true
now, since I haven't been able to abandon Forward Euler. I have to make some
major changes in my code to allow this and other things...

Some weeks ago I was a totally unexperienced cloth programmer too!!! You
learn many things while you walk in this bumpy road!

Thank you very much again for your compliments,
