Oh man laser outfit... I sure want some.  That link gives pricing for
1-10, maybe if we end up wanting a bunch more they might provide a
further discount?

I wonder if one could have a built-in smoke machine emitting particles
along with the laser beam for best viewing.  I saw a smoke machine on an
outfit over the weekend, I will see if I can contact the maker of that
and get more details.
