“Please Leave A Message” is an interactive workshop window installation. People on the street can access it via Wi-Fi, with their smartphones, and write positive, encouraging notes on it for the other pedestrians to read. Watching the messages being written is quite fascinating, as they are accurately drawn by the beautiful mechanism of a 30 year old “Aritma Colorgraf” pen-plotter on a large roll of paper. Later, the installation was updated to allow drawings pictures.
