I wrote about advertisimg teletubbies before, and here's a (sort of) new twist: Media Post profiles the Adwalkers. The novelty of the twist is primarily in the kevlar-looking outfit. Adwalkers are also interactive. "They walk around in public venues where the client's target audience is likely to gather, with the client's message beaming from their chest. These psuedo-cyborgs invite conversation, then interaction, through games, contest entries or special offers. They deliver both engagement and the ability to measure response."
