At first glance it appears as if all of Philip K. Dick's worst fears about advertising have suddenly materialized in the middle of Shinagawa station, one of the busiest train stations in Japan. The main character featured in a Suntory advertisement for black oolong tea, with purported health benefits, seems to follow each and every passerby looking them straight in the eyes.
Of course it's an optical illusion generated by carefully creating the characters face with a concave shape - kind of like looking into a bowl. Nevertheless, the effect is quite spooky.
Will it help Suntory sell more tea, or drive people away? I'm not sure. Still, it's generating quite a bit of buzz here at the moment.
