Evoc is a German outdoor sports brand that has developed a shock absorbent backpack that could help prevent spinal injuries.
Without much of an advertising budget the company decided to create an interactive “Indestructible billboard”. Passers-by were challenged to hit a backpack as hard as they could and the results of the power of the hit was displayed on a screen. A camera also took pictures of the moment of impact and people could post these photos to Facebook and share with their friends.
