DRoPS is a reactive light installation.

Organic illuminated objects are deployed in the darker, rather unsafe corners of the city. Left alone, the objects calmly breathe light. As a person approaches a DRoP, the DRoP becomes nervous, speeding up to a state of hyperventilation. DRoPS plays with the subjective perception of safety in urban environments. The first set of three DRoPS is mounted inside a pedestrian autobahn underpass in Lucerne, Switzerland.
DRoPS is part of a series of artworks to sanitize certain areas of the city and is supported by cultural funds from the city of Lucerne.

The initial concept was conceived by Andreas Wiegand. I was responsible for the technical implementation which included the microcontroller programming and the design of electronic circuits for the installation. DRoPS uses an ultrasonic range finder to sense its environment, a custom algorithm transforms the sensor readings into a vibrant pattern of light.
