**** Oh come on!!! You really have no ideas about how to use something as
nifty as a stereo pointer? Is this a discussion group for stereoscopic
topics or not? What makes a stereo3D picture more useful than a 2D one
(assuming a stereo interested observer)?
They say Gingko tea is good for the brain... :-)
Think of the pointer as a 3D light paint brush. The question isn't *what
could possibly be done with it* it's more like, *why wasn't this thought up
a long time ago?* This idea has far more potential than has been discussed
so far!

***** So darken the green one a bit with a filter material till each beam
has equal brightness for the circumstances. Or use a more powerful red laser
than is used for the green. It seems filters might be the more accurate way
to calibrate them. A polarized system wouldn't have this problem.
