The light art installations bring former residents of the historic city centre to life. This is because artist Alexander Reichstein believes that people never really disappear without a trace: “We can still hear words, footsteps and even breaths made long ago. People from the past wander around the park, meet on the street and enjoy the fresh air on the balcony.” In the UV light, the figures, made from bent wire and sprayed with fluorescent paint, come to life like ghosts. These translucent figures merge with their surroundings, and the environment of the old neighbourhood becomes part of the work. The stylized figures are reminiscent of line drawings, but are three-dimensional.
