Listening Posters
What if we could make posters that only showed up when sirens were nearby? Using world first audio detection technology, we programmed billboards and bus stops around London to listen out for sirens. If one was within earshot our messages were deployed. Messages from real mums, who had concerns around their child’s safety.
These siren-triggered pleas cut through the noise, and passed on a message that if you won’t put your knife down for you, put it down for your mum.
