> >Ohhhh Kaaayy... Interesting discussion about the harmful effects of laser >light, guys, but I think the point was this was a *projection* display >(check the subject line). So it would be an intense laser light, but no one >should be standing so they could see into the beam at all (as they'd be >blocking the picture.) ...and also, if it was a retinal display, the length the beam has to travel is so short, a simple LED will provide ample power/luminosity/sharpness....but why would luminosity be a problem for a laser? I can see the reflection of a 5mW laser pointer on white concrete a mile away at night...assuming a better, HeNe laser and some mild focusing optics, one should be able to draw on an overcast sky with not much more than 5 to 10mW. (The local casino had a trio of spots tracking the sky once...thought we'd like to one-up them...;) -- Eric LaForest Nascent Linux Borg -www.ncf.carleton.ca/~di458- #define Hacker !(Cracker) //FYI: http://sagan.earthspace.net/~esr/ Breaking into computers does not make one a hacker, for the same reasons that hotwiring cars does not make one a mechanic... paraphr. from ESR -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.ml.org
