Sphere Eversion Re: AutoOpenGl Plugin

Hi,

I found some application field for AutoOpenGl Pligin.
It is a creation of show of so-called sphere eversion
http://torus.math.uiuc.edu/optiverse/code/

Native code (avn.exe) uses old version of glut32.dll and eats CPU 
time very much. 

Other useful link about the sphere eversion:
