Save a Life on a Bus-Shelter Ad

Here's a clever take on bus-shelter advertising from agency Ig2 in Quebec, courtesy of Ads of the World. Passersby hear the tell-tale sound of a patient's heart stopping and see an outline to place their hands on his chest. When they touch the display, they hear a healthy pulse. The point? To encourage more people to consider a career in medicine, where they could help save lives. It's an incredibly simple way to visualize a complex idea.
