My idea is to present ZocDoc to people as a simple and easy way to find a doctor when, and where you need one.Finding a doctor and making an appointment by using ZocDoc is as easy as booking a room, or a flight.So go find your doctor,or as I like to say:  Zoc your Doc!

UPDATE: Billboard Visualisation - on second slideI think it would be great to put a "No need to knock, just Zoc your Doc" billboard in waiting room, and below it touch screen where you can find a doctor and make an appointment right away.
