Just about one of the coolest uses of LED is this wall in a Norway pedestrian tunnel that was lights up when you walk by. It was made for by Stig Skjelvik and Snøhetta architects in collaboration with Prototyper AS and Rasmus Hildonen for the European Capitol of Culture 2008 event. Called the Dobpler, it is an interactive LED display wall that is activated by movement.
Watercolours, the project website for the installation in Sandnes states:
Sandnes’ city centre is split in two parts by the railway line. A new, creative illumination of our railway station subways will give us safer traffic and walkways. The subways become lighted portals, pleasant to use, mirroring the users who can observe themselves and others as active elements of the township.
The coolest part? It leaves a trail of light behind you. Check out the Video
