'please watch your step' by japanese artist yasuhiro suzuki was one of four public installations organized by the digital public art project at the haneda airport in toyko. suzuki's floating human shaped balloon was an experiment in getting users to participate in public art. for many, airports can be a place devoid of human emotion with its vast size and long waiting periods. this site intervention hoped to evoke a positive response from by passers and provide an element of humor and surprise to their journey.
