Weekend fun

Warner Brothers Canada turned to Lowe Roche to create two billboards that functioned as giant petri dishes which were then injected with bacteria. Over the course of a week, the bacteria grew to form the name of the movie being promoted, the Steven Soderberdh film Contagian.

The agency teamed up with microbiologists and immunologists from around the world to create a unique bacteria message board located at 409 Queen Street West in an abandoned store-front window. On 28 August, two large Petri dishes were inoculated with live bacteria including penicillin, mold and pigmented bacteria and almost overnight have revealed the true Contagion -- an artistic interpretation of the spread of a virus as depicted in the film.
