In a recent blog post I wrote about “Hidden peanuts for elephants” – zookeepers that hide individual peanuts in the elephant enclosures in zoos, to keep the elephants amused and occupied as they – supposedly gleefully – search for little peanuts to eat.
I could not help but think the same thing was happening to humans when I stumbled across this interactive display at the Zurich International Airport (ZRH):
There are three buttons on the ground you can press with your feet. When you press them, this controls the video advertisement you see.
In the end, at least the elephants got something to eat.
