Rorsketch is a public collaborative art project that allows MoMA PS1 visitors to draw their interpretations of clouds on a digital interface on the rooftop. Using data gathered from visitors’ smartphones, the drawings will be automatically tagged with the sketcher’s name, age, profession, and country of origin. People can view the most recent interpretations in the courtyard. A gallery of these drawings with their metadata will be displayed in the two adjacent alcoves. These drawings will be documented online.
