An original viral (or rather, fungal and bacterial) marketing campaign for the movie Contagion. Although the film tells the story of a fictional viral outbreak, the marketers of Warner Brothers Canada kept it in the realm of microbiology by teaming up with 25 microbiologists and creating what is probably the first agar-plated billboard, which they placed in a storefront in Toronto. The bacteria and mold were plated and grew in the letters, but it looks like contaminants formed their own random colonies, purposefully creating a rather eerie effect. Thanks to Zack Moss, a student in my lab, for pointing me to this. More details in the Vancouver Sun.
