"Located in the central Navigli area in Milan, a special animated poster has appeared allowing fantasy to replace reality. Among colourful balloons, Sunny, Hitch, Izzy, Pipp and Zipp will appear sliding down a rainbow and flying out of the ledwalls frame with an amazing immersive effect for people walking along the road."

The article has a few other short videos, including a Hitch Trailblazer turnaround, a video of the ad being played on the screen, and a workflow example.
