Five urinals and five video screens are placed against the façade of the Mediamatic Biotoop. The screens display audio-visual artworks created by Kamiel Rongen and with the urinals, we collect the urine kindly donated by visitors. Whilst the films may appear digitally created, they are entirely natural and made with a most natural ingredient; the artists' own urine! Taking inspiration from the softer golden colours of urine, Rongen froze his urine before adding it to many different types of oily substances. The ice, pee and oils all react with each other to create a world where gravity constantly changes, and Rongen organically follows these reactions. To make the experience complete, Rongen composed soundscapes to accompany the act of peeing.
