Based on simple chemical reactions of photochromic pigments with UV Laser Light, the installation literally draws continuously onto the Urban canvas. The project is split into three canvases that are drawn upon at the same time with three simultaneous working machines. Two are permanently marked by the laser, while the third one consists of two layers of one fading and one permanent layer of photochromic chemicals. The half-life of the fading pigments agitation is around 2 minutes, only to be replaced with a further animation layer. The second layer is permanent and becomes reference to the first. Each line, drawn with the precision of a surgical knife fades slowly away while the set-up continuously repeats the drawing onto the canvas. A camera is recording the drawing processes, revealing the animated drawing, created by the repetition of a palimpsest like layered chemical reaction. Just as the fading and disappearance of Graffiti is part of the medium that it gets overwritten and replaced, Liquid Light is a continuous fading process that through time-lapse and camera filming allows this temporal argument to be part of the Graffiti.

Studio Tobias Klein is a practice, operating in the between of architecture, across the fields of art and installation, experimental design, interactivity and sculpture. Trained internationally as an architect, his work maintains a fascination with the construct of space, while questioning the modern image of its understanding, instigating a re-positioning between embodiment, perception and projection. The works constantly evolve between static and dynamic models, shifting from objects to installations and design, prospecting new visual territories in the field of narrated embodied space.
