Light Blaster
Christian Moeller
Brief description of the work:
Interactive light and sound installation; laser beam directed by user's heartbeat measured via pulseoximeter
Materials, dimensions, duration:
The side of the installation, which faces the viewer, is made up of a 4 by 5 meter square wall of light. A water-cooled 4 W argon laser scans this plane of light into the space by projecting its blue-green laser ray via glass fibre light conductors onto a highly reflective surface mirror positioned at a 45 degree angle and rotating at 2,000 rpm.
Location (venue & dates, public/ private):
Exhibited at Design Horizonte in Frankfurt's Naxos Hall, Germany 1993
Audience information (size, mode of participation):
A sensor communicates the viewer's pulse rate to a computer. The signal moves the light plane backwards and forwards in a motion that corresponds to the pulsation of the viewer's heart. The loudspeaker system behind the wall of light transmits the sounds of heartbeats, thus supplementing the pulsating motion of the wall with acoustics.
