I was lucky enough to see a talk from Improv Everywhere's founder, Charlie Todd, at the Cannes Ad Festival last year. What he and his team do is just brilliant! Probably why so many ad agencies, ahem, "borrow" his ideas for brand activations. Well, the word is that as part of Design Indaba this year, the MP3 Experiment (based on the video above) is coming to Cape Town. Follow the link for info on how you can join in or RSVP on the facebook invite. Be at Camps Bay at 15:00 on the 20th of Feb to catch all the fun.
