from the other topic:
the way ours and animals depth perception work is by triangulation
thats very different to the AUGMENTED reality from nintendo 3ds for example
this varying depth stereogram may make you understand:

the thing is that im in a position to say my (our) perception is flawed since i managed to have an augemented depth perception some times in my life for seconds
i think that if i learn to keep that augmented perception, i know how to do it but its so difficult, ill have a four dimensional percpetion and achieve enlightenement
i think the philosphers stone which im after is nto other thing but an eye exercise to achieve binaurality, enlightenement, four dimensional perception
thats what i do to fight famine in the world
