UK based installation art collective Greyworld have been making interesting sound projects in urban space since the late 80s. Their most recent project, “The Game” turns London’s Jubilee Gardens into an interactive birds-eye-view portrait of Alfred Hitchcock. Sensitive tiles in the space create sound, imagery and light arrays based on visitor’s movements. The space is intended for both interaction and contemplation, although collaboration is key to get the full effect. If you’ve been to the space, post a comment and tell me about it..
