Maybe it is the grid pattern, but I am not entirely convinced. The more
blurred patterns in the background seem at first glance to be 'larger'
than the non blurred ones in the foreground, which is not the intention
of course. The idea however, is particularly interesting. By
blurred-with-distance I would perhaps understand more a 'simplification'
of the pattern rather than a 'blurring' like this. I don't know how to
express this correctly. You are probably on the right track though, but
it needs more thinking (at least for me).
