In the workshop, we will learn how to program and use a laser projector that can be used for the purposes of light graffiti or outdoor art interventions. The focus will be on a DIY approach that is based on controlling the laser with audio signals, but we will also learn about different (both hardware and software) approaches. We will draw graffiti with our mentor Tadej Droljc in vector graphics programs and then import them into a specially designed BeamShaper application. We will project the final works onto public surfaces in a guerrilla campaign with a van and lasers. The number of places at the workshop is limited, prior registration is required.
