But a temporary project has also been started that makes use of projection mapping: the technique in which objects or buildings are used as a projection surface for video projection. Artworks projected onto the contours of the building were displayed in the Cloth Hall of Ghent (the historic building where the cloth trade used to take place). No images of the original Ghent Altarpiece, but a contemporary version made by artists. Every two days an extra panel was added, so that it also invited you to come back again. A form of art that everyone (tourists and residents) can enjoy as soon as it gets dark.
