Thats cool, iZ3D has free support for red/cyan glasses just like NVIDIA's 3D vision.
Im so glad I kept my glasses from shark boy vs lava girl.
Does not say how you get 3D in OpenGL though.
EDIT:
Looks like iZ3D does not support OpenGL games... only quad buffered OpenGL which is only available on the FireGL cards! That sucks cause NVIDIA has supported 3D OpenGL for at least 7 years.
