It makes me shudder to think that this dangerous knowledge is now unleashed on the world . . . .

Another caveat is to be careful of reflective surfaces. When using this, you may instinctively avoid pointing it directly at yourself or another person, but you might hit some unnoticed shiny surface and bounce enough energy into someone's eye to cause trouble. Also, while a limited exposure may not "blind" you, it will probably kill off small bits of your retina each time. Your brain will do some error-correction so you won't really notice it, but repeated damage will have a cumulative effect. Please be careful.

On another note, what I'd really want would be a combined red "pointer" laser with a "burning" laser. I could then get a lock on a small target (a cockroach or a fly sitting still), then activate the burning laser to kill it. Maybe a timed switch would prevent me from messing up my aim when I make the switch over. So, find the insect, press the timer switch to activate the pointer for 5 seconds. Lock on the insect in that time and hold still. Burn the insect when the DVD laser kicks in for some predetermined time.

Many invertebrates, including insects, are unable to see red light, and so are not disturbed by a red laser pointer.
