About the artwork This action stems from a time when Harald Naegeli caused a stir as the so-called “Sprayer of Zurich” by illegally spraying pictures onto public walls around the city. Today, he is regarded as a pioneer of graffiti art. Naegeli himself described the mysterious figures with which he populated the entire underground garage as “cave-dwellers”. Originally, there were further works by Naegeli on a number of ETH Zurich buildings, but these were eventually removed.
