When a Japanese robotics pioneer first described the "uncanny valley" of creepy objects, he filled its imaginary depths with human cyborgs, corpses and undead zombies. But four decades can change a man — he now finds the faces of dead humans and Buddha statues more comforting than the faces of the living.

Masahiro Mori created the uncanny valley metaphor in 1970 to suggest how artificial figures can steadily seem more likable as they appear or behave more like humans, but only up to the point before their likability takes a sharp plunge into creepiness. His metaphor has since become a common explanation for why android robots or Hollywood's latest computer-animated films can creep people out rather than win their hearts and minds.
