Anyone here with a good high-res SRL which can do enough IR detection to check if indeed this is the case ? I guess a fun test would be to use a mirror to project a few extra pixels onto a flat area - and see if that area suddenly jumps 'forward'. > >Thanks, > >Dw > > >0: http://www.wired.co.uk/magazine/archive/2010/11/features/the-game-changer and all the mystification on how they work. >1:http://www.zimbio.com/Popular+Topics+in+Astronomy/articles/vnjstT2fTM2/Green+30mw+Laser+Pointer+Pen+Style+Star+Holographic >- >Sent via the backstage.bbc.co.uk discussion group.
