Belgium: Art installation uses laser pointers to trigger visuals, play music in a church

Hand-held laser pointers are used to control music and trigger projected visuals, in a 2013 art installation in the Royal Chapel of Protestante Church in Brussels. The church’s architectural elements were specially projection-mapped. Detectors see the laser “dot” and use this as input to an “interactive virtual musical instrument,” where different locations map to different instruments and melodies. In addition, video projectors are triggered to illuminate areas near the laser dot.

The laser pointer coming from lower left leaves a trail of falling “stars,” while the laser coming from the right triggers a glow on a ceiling beam plus a video to play on the ceiling.

The installation, Archifon II, was created by artists Tomáš Dvorák and Dan Gregor.
