We were able to use our digital graffiti wall during an event of the Hamburg Chamber of Commerce. On location in Hamburg we installed a wooden wall containing 2 large digital graffiti screens. We also provided the wooden wall with a painting showing the Hamburg skyline and other Hamburg-related images. During this event, local entrepreneurs and politicians, including Ursula von der Leyen, President of the European Commission, were able to write down ideas and suggestions on the graffiti wall about how to work more climate neutrally in Hamburg.
