In this engine-powered installation, a speaker is mounted onto a rotating arm that is several meters long. Like a watchdog, the machine scans the surrounding space for visitors. Closer investigation would be tempting fate, with the rotating arm swinging so powerfully round. You hear the impressive sound of the mighty motor turning faster and faster. You can feel the displacement of air as the speaker whizzes past you, and you better step out of reach. The machine slows down and you start exploring the space, with your movements manipulating the sound it produces. Just don't get too close!
