Now you see it; now you don’t!

Lego asked us to produce a mall poster that would make consumers take a second look (and third, and fourth)…
When you first looked at the poster, you could see the Lego character in the forest scene, but after taking three steps to the left or right, the character disappeared!
Another three steps further and the character appeared again. People walked back and forth to see the effect, each time internalizing the Lego brand!
