When we look at an object, both of our eyes see things just a little differently as, in fact, both angles are different. Yet, inside our brain the two images are combined into one. “Diplopia” is a stereoscopic light object built on this principle. The Onionlab artists subsequently applied their mesmerizing imagination on the façade of the Catharina Church, in 3D! You may of course view this work of art in 2D, but those who would really like to submerge into the world of Diplopia, are advised to buy 3D-glasses. Though it entails a little, extra expense, you will enjoy it so much more! Those who, prior to - or directly after - the projection, look at the impressive facade of the Catharine Church, will see the image belonging to a city in which technology, design and knowledge come together. Onionlab is a multidisciplinary studio from Barcelona, consisting of a cooperative team of designers, engineers and artists. They are specialised in creating spectacular audio-visual art shows, sometimes making autonomous work, yet more often working on behalf of organisations in the field of technology, design and art.
