Google's 'Project: Re-Brief,' created by Johannes Leonardo and Grow Interactive, revisits old-school favorite ads from Coca-Cola, Volvo, Alka-Seltzer and Avis, and translates their message into various digital formats -- showing off Google technology in the process.

For example, Coke's classic "Hilltop" ad featuring the familiar jingle "I'd Like to Teach the World to Sing," which already underwent a modern-day makeover in 2005, becomes a display ad through which online viewers can send digital greetings to someone in a city of their choice.
