I've also brought up a wingsuit idea in a forum thread
viewtopic.php?f=4&t=15483 that would also involve cloth. maybe someone could start with simulating a piece of printer paper in the wind, a flag, or a wind sock and go from there, I put in 'open source cloth simulator' and found some code and algorithms, in opengl [ex: opencloth;
https://code.google.com/p/opencloth/]. I think a cloth simulator engine would need to be written, that behaves independently or even could interact with metal objects?
The code for the current hanglider wing, paraglider parachute and all people simulation clothes, such as for the skydiver, may need to be rewritten/expanded upon. Unless it is already?
peace.
