The Sonar festival is over, but there are some more projects from the exhibition which are worth looking at. Like Sound Walk, a 'human sequencer' created by Julio Lucio with music written by Nikka. 

Visitors walk through the space to interact with the installation, creating the music as they move along. A projector creates the images on the floor, and while moving though the space, visitors get visual feedback as well, as the video clearly shows.
