Hi,

The following web page should answer your question:

http://pymol.sourceforge.net/stereo3d.html

On a related note, I recently came across a new 22" LCD stereo system which
is below $1000 and requires polarized glasses ($10 each). It doesn't seem to
be set up for OpenGL yet, so isn't suitable for Linux. I am curious as to
whether anyone has it running on some DirectX molecular visualization
software in Windows:
