This is such a great modern art installation. Live webcam streams of landmarks from Denmark, Amsterdam, Berlin and Holland are projected onto physical 3D models of the landmarks.

The result are four “live-models“ of a distant space, which can be regarded three-dimensional and are touchable. With this material manifestation, the transmission, in contrast to the usual webcam, where it remains virtual, is completed. The viewer adepts the webcam-stream as “real“.
One of the great things about the set up is that the images come from 1 projector which is directed towards 4 differently angled mirrors which then project the image onto the 3D sets.
