David on Demand was the first ever Twitter driven experimental campaign that broadcasted live 24 hours a day for six days at the Cannes Lions International Advertising Festival. Leo Burnett creative recruiter David Perez became David on Demand by sporting webcam enabled glasses that recorded and broadcasted his experiences live on his website, while doing anything asked of him just by tweeting @davidondemand. This was the highlight of Leo Burnett's Wildfire presentation which also featured a huge interactive display screen showing the conference through David's eyes, video from around the world, streaming in realtime tweets and trending topics.
