Future façades will become three-dimensional displays. New developments in display technology, so called voxels allow revolutionary architectural expressions. Whereas spatial expressions till present were determinated by the physical attributes of the building material, voxel displays will shift these borders. An intangible material, light points, defines space and allows surface attributes, such as: Dynamic relief, multilayered surface, decay function, privileged perspective, movement and speed and design process. By the example of spectacular contemporary projects, the book presents recent developments of three-dimensional display technology, showing its significance for our understanding of space and architecture.
