[photo-3d] something wrong in our eyes

["Sergio B" <winter@xxxxxxxxxx>]

well I believe 3d illusion depends upon the circumstance that indeed there's
something wrong in our eyes. red/blue focussing at different distances, some
slight refractive difference between the 2 eyes: some slight disparity in
astigmatism can be enhanced by the tiny lines composing the letters.
anyway opposite illusions are an additional interesting phenomenon!
