[photo-3d] VR-Joy LCS glasses (was Re: LCS Mac software)

[Chris Bruns <cmbruns@xxxxxxxxxxx>]

  1) The VR-Joy device does work at 640x480.

  2) It also works (as expected) with a graphics card that does not support
interlaced modes (Diamond Fire GL1000 in my case).

 3) VR-Joy will not damage your monitor - the vertical refresh rate is not changed.
It simply sends black lines alternately to the odd and even scan lines of alternate
frames.

  4) It also works well for applications that have a strict frame-sequential stereo
effect.  The game "Descent" is excellent in this regard.
