Here's a fun interactive installation that Brazil's AlmapBBDO did for Adweek sister magazine Billboard. The digital poster prompted users to select, out of a larger group, three musicians whose music they most identify with or have been influenced by. The poster then created an image of the user made up of small pixel-like images of those musicians. The tagline is: "You are made of music." See some of the user-created images over on Flickr.
