Anything dark enough will work.  I used a pair of sunglasses, holding
one of the lenses over my right eye.  The dark lens causes the image
to reach the right eye just a bit later than the left eye.  Coupled
with motion of the image, your brain interprets this as 3-D.

Did you notice how the commercial and the pre-recorded bits seemed to
have a better 3-D effect than other parts of the halftime show?
Those parts had large objects moving at a relatively constant speed
across the screen.

In fact, any TV picture with enough contrast and large-object motion
will produce the same effect.  Try your "glasses" the next time you
watch any TV program (sports and shows with lots of "action" give the
best effect).  

I have a feeling that since this technology is so simple, we'll be
seeing lots more of it.
