Imagine – you can influence a huge wall of blue lights just with your hand. Then, at a certain point, you push a button and freeze the picture. What you then see is yourBlue or in German DeinBlau. We will take this moment and add it to a big picture, a collage of thousands of tiles produced by all the visitors of the exhibition. So at the end you are a part of a big piece of art. Wouldn’t that be great?
