SPATIAL SOUND Rotterdam, 2000/2001 - invited  
Spatial Sounds (100dB at 100km/h) is an interactive audio installation by Marnix de Nijs and Edwin van der Heide. In this engine-powered work, a speaker is mounted onto a rotating arm that is several meters long. Like a watchdog, the machine scans the surrounding space for visitors and you had better step back, well out of reach. You will hear the sound of the mighty motor revving up; turning over and over; faster and faster. You will feel the displacement of air as the speaker rushes past you. it’s a game of attraction and repulsion between machine and visitor and with a rotating arm swinging with such force and power, closer investigation could be simply tempting fate. When people enter the room they are immediately detected and the machine is directly influenced. It reacts both musically and with gestures.
