how to see stereograms

[pixel]

hi

for those who still have problems with stereograms i made simple schema to explain how to see SGs

ofcourse real SG has hidden picture
but in general every repeated pattern can be seen as SG
even striped wallpaper even tablecloth
and it doesn't matter if pattern is dotted striped or anything else
if you know how to defocus you'll see 3D effect

i hope my schema will help with great stereograms
(ie gary's ones)

EDIT: i added third frame to expose sledger's way of looking at SGs
