To change this, we used a technology that brings a traditional print ad to life by showing the fascinating underwater world in 3d.

All they needed was a smartphone with QR code reader and a piece of plastic film, which was sticked on the ad. By bending the film into a pyramid and placing it on their mobiles, people created a mini-aquarium with its underwater inhabitants as a 3-D projection.

With this "interactive" print ad in magazine ZOO.F we reached over 50.000 children and their parents in the Frankfurt region. They were all fascinated by the 3-D "Holoquarium", with the result that many of them wanted to see the underwater world live in person at Frankfurt Zoo.

A documentary video of the "Holoquarium" spread itself worldwide via social media and generated many likes and posts, but also many new fans and friends for the Frankfurt Zoo.
