Surely you have already seen such projects when the projector turns the facade of a building into an interactive screen, drawing on it patterns, paintings and changing the texture and shape of the building. But recently I came across the most detailed implementation of this idea (at least from what I had met).
This is the project “555 Kubik”, established in Hamburg for the building “OM Ungers„ Galerie der Gegenwart “”. It looks so amazingly vivid that the projector basis of this effect is not felt. It is interesting to find out how the sound is arranged there, but I think it looks alive at 100% realistic.
