> Strange, when I direct a laser pointer towards a wall I see a point on the wall and thats about it.Actually, you are seeing reflected laser light. That's what is hitting your cornea. If you didn't see reflected light, you wouldn't see anything at all. Well, you'd see the light reflecting off the wall, but not the laser light.
Interestingly enough, the FDA regulates laser based devices for safety concerns.
http://www.fda.gov/cdrh/
That's the "Class 1 Laser Device" you see on CD and DVD players. Part of the Class 1 spec is the device doesn *not* radiate laser emissions. They aren't powerful enough to burn you, but they could theoretically hurt your eyes.
So, on a high end CD player where the transport is well sealed against light leakage, the odds of laser light spilling out are slim. The odds of light escaping, bouncing off random walls and objects, and hitting the Intelligent Chip are astoundingly slim. The odds that those photons carry enough energy to do something useful are close to nil.
Not buying it.
