Shadow Harp

Interactive installation in The Old Church (de Oude Kerk) in Amsterdam as part of the Tropistic Manifestation in 1994.

 A powerfull blue laser drew a web of light above the ground. When a ray was interrupted, a channel of a 16 track music composition was triggered. So one could walk trough the grid of beams, perhaps unaware of the consequences, or play it as a giant instrument.
