well
today I have learnt that the optimum relationship to give strong depth illusion is...
if the spacing of the lines on the top layer is 13% denser than those on the bottom layer, the lines appear to rise
if the spacing of the lines on the top layer is 13% denser than those on the bottom layer, the lines appear to fall away
however, a key difference seems to be in the overall density or tone given by the lines in the top layer relative to the density of the lines in the bottom layer. I should be able to check that in Photoshop...
