from dust till dawn
Installation for Empty Urban Spaces

'Dietmar Offenhuber Dietmar Offenhuber / 'Markus Decker Markus Decker

The dust and atmosphere of empty urban spaces constitute the medium of interaction in this initial experimental setup. A grid of laser lines just above the ground produces an initially invisible, contiguous light surface. Objects and particles that break through this surface—for instance, dust, cigarette smoke or larger objects-are highlighted by the laser and become visible as a surface or an outline. The outlines and dust patterns are registered, and an XY-grid synthesizer turns their two-dimensional movements into dust pattern sounds. Each step a visitor takes—indeed, visitors' mere physical presence-sets the air into motion and causes dust to swirl up. What this actually represents is a fragile interaction medium that is exceedingly difficult to control, and one that eliminates the non-binding aspect from the concept of tangible media. We strongly advise against wearing clothes that would be adversely affected by contact with dirt.
