Creative Billboard lets you STOP Child Abuse.
This interactive billboard locates on a sidewalk in South Korea. It shows the silhouettes of an adult man threatening a child with a bottle in his hand. Interestingly, passers-by can step up, creating a silhouettes between the empty space, symbolizing a step-in to prevent the child abuse incident.
The message on the ad says: “Child abuse, you can prevent it”. When someone steps in between, a superhero-like logo
appears on his/her shadow with an emergency number and a line: “Report to become a hero for children”
