Well, not really.  The basis for the 3-D effect used for this half-time
show (as well as the much-publicized episode of "Moonlighting" last season,
although I think that that wound up canned due to the writer's strike) is
slightly delaying the image to one eye.  While this provides a "sort-of"
3-D illusion, while not mucking up the image for "non-3D" viewers, the chief 
drawback is that it ONLY works when things are in motion on the screen.
Once the image becomes static, it goes flat.  Too bad, that.
