No, you didn’t have so much to drink last night that your mind is still playing tricks on you! This is actually an LED installation that responds in real-time to your steps. From now till October 25th, the people in Berlin who dare to walk over it at the Hauptbahnhof train station, will take part in an interactive installation called ‘Onskebronn’ (Norwegian for ‘wishing well’). It was created by German Sven Beyer of the performing arts group Phase 7. Coolest part? Not only do you get a trippy visual experience, you get another sensory surprise. Sound is also triggered by the movement of people stepping onto the platform. via [Yahoo! News and Switched] pic by AP
