The initial project for this projection mapping took place in a workshop with Benedikt Groß and Joreg one year before the actual anniversary. At this time the projection was mapped on a 1:50 model of the original building. With the help of two projectors it was possible to create a stereoscopic image – a 3D illusion. This illusion only works from a dedicated viewing angle. One year later more projections were created and finally projected on the facade of the real building.
