Polish-German artist Karina Smigla-Bobinski gives buoyancy to the act of drawing with ADA, a large inflatable drawing tool. Filled with helium, ADA floats freely, making lines with its charcoal spikes as it moves through a room. More dramatic mark-making starts to occur when humans are added to the mix: the video above shows visitors engaging with ADA at Muffathalle where it was installed for a week in Munich, Germany.
