In the halcyon days of 1993, schoolchildren across America were suddenly stratified into the haves and the have-nots, the gifted and the peasants, the Illuminated and the blind. The dividing factor? Those who could see the stereogram images in Andrews and McMeel’s Magic Eye books, and those who could not. (The emotional devestation of this conflict was best captured in Kevin Smith’s 1995 documentary Mallrats, in which a hapless young man is driven to madness by his inability to see a simple sailboat.) For years, rumors swirled on the playgrounds of Earth about how these dark magic portraits were crafted. Elf-hair paintbrushes dipped in unicorn blood? Satanic rituals backmasked into Rush records? Computers, maybe?
