shutter glasses for use with powermac g5

I am interested in using psychtoolbox to present simple displays in depth.

I am using the latest psychtoolbox with os x 10.4.10, nvidia 6600 le, viewsonic p225f crt
screen.

Does anybody have experience of using a powermac g5 with a nvidia 6600 to drive lcd
shutter glasses?

I have seen mention of both the stereographic crystaleyes and the nuvision 60GX, in the
forum, but always with different hardware.

In particular is it possible to interface the nuvision set up with my hardware, or do I require a
better graphics card?

Any advice gratefully received

Kevin
