Berlinengineer Sara Reichert für EinsteinsTraum by Xin Wei Sha "Sara Reichert" <sarareichert@web.de> a project with one of the Olafur Eliasson students Fernanda and me constructed a water curciut system that interacts because of 20 ir- sensors with the movement of the people in the room. The dynamic of the pumps were controlled by a microcontroller. We followed the plants on the 9m hight ceiling with transparent waterpipes and the water came down through invisible tiny holes into a messing funnel. The sound of the falling drops were amplified.
