Peter Dodds sent me 5 nature stereograms that work if you look at them crossing your eyes. I have most succes with these, since some I never managed to see. Here’s what Peter wrote: “Here’s 5 more stereograms…about nature! I searched Specifically for cross-eyed stereograms, so these wont work by relaxing your eyes.” Which stereogram you like the most? Spider one is little scary, but I like the spiral plant one the most! For more Stereograms, visit appropriate “Stereogram Category”.
