A long long time ago when I was applying to study in Universities, a
lecturer
showed us a demonstration with a laser. As an aside, he told us to look
at
the pattern projected by the laser onto the wall and do something which I
forget (move your head from side to side or something), and if the
pattern
stayed still you had 20-20 vision. Does anyone know the details?
Haven't heard about that. Is it supposed to test acuity?
With PHucker & lasers - its a test for stupidity.
Do not look into laser with remaining eye.
That tree in my front garden I posted a photo of recently, I think it's dead. Might have to tow it out - being in the front this could be fun. I shall set up a video camera.
