In the US, firearms have become the main cause of death in children. Change The Ref, an activist gun reform organisation, decided to transform the most innocent and iconic symbol into a stark reminder of gun violence. Every time people scanned any school bus, moving or still, they would unlock the story of gun violence for children. They were then redirected to an online museum that featured real objects belonging to children who were victims of gun violence, inviting them to take action against politicians immediately.
