I've been behind on my digests, and rushing my reading.  I didn't notice
any comments on my plans.  Is that because I've planned to do something
conventional!?  How horrible!

If this sort of projection is common, by what standard are projected slides
adjusted?  I thought adjustments were always made to set the stereo window
at the screen.  Does the projectionist instead try to judge infinite
points, and set them to be 2.5 inches apart on the screen?  What if there
are no points at infinity?

I do need to figure all this out before August!
