Infectious 'Contagion' Billboard Is Made of Bacteria

Here's a disgusting but cool out-of-home ad: Warner Bros. Pictures Canada hired microbiologists and immunologists to create a one-of-a-kind billboard made of growing bacteria in an abandoned storefront window in Toronto—to promote Steven Soderbergh's movie Contagion. On Aug. 28, the scientists inoculated two large Petri dishes with live bacteria—including penicillin, mold and pigmented bacteria—which rapidly grew to spell out the name of the movie on the board.
