I didn't ever expect to say this about an SGI, but that truly sucks.

I have a pair of Sega shutter goggles (from the Master
system) somewhere.  I never hooked them to anything though.  I tried a
stereo head mount display once (on an Onyx with MCO no less), and was
unimpressed with the results, so I never got around to getting my shutter
goggles to go.
