Jerry,
I saw those at the winter meeting. They are LED and do work pretty well
for color mixing and as ray boxes on a table. I would like something
brighter for use on a larger scale--like with a group of 100 kids.

(and, Duh, now I just realized what Bill was saying---Of course the laser
beams need to be divergent for a ray box--I hope they include that feature
on the laser blox--they hint at it in the description.)
