Interactive installation in a velvet chamber. Immersive projections of beautiful particle trails, filmed from my own cloud chamber experiments, make visible the activity of cosmic rays and background radiation that pass through us continuously without our awareness. Through experiencing this usually unseen activity of particles that shower down on us when cosmic rays strike the edge of the earth’s atmosphere we can begin to think about other possibilities of what might be present in our universe that we are currently unable to interact with such as dark matter.
