Dust is an interactive video projection developed in collaboration with Marcelina Wellmer. The installation shows 5000 dust particles that move elegantly in response to a “gust of wind” created by the audience. The motion of the observer is tracked to agitate a fluid simulation that mimics the behaviour of air. All particles are hand draw by Marcelina based on her previous photography and canvas based artworks. The software is created in processing, C++ and C# and uses a Kinect 3D camera with custom directional motion tracking.
