Oh man, that is too funny. My original came from a picture I took off the side of a transformer when I was wandering around at OSU one night.
That laser safety one reminds me of a story I heard about a professor (Organic or something, not the kind of guy who usually handles lasers) that decided that since only something like .01% of his laser power came through the back of a mirror, he should be able to align his beam by eye. It turns out .01% was in fact plenty to make him blind.
