Great example of how to engage people with simple and ingenius ideas. Done for NGO Misereor, it turns the act of donation into an experience.
Watch the video. It’s a lovely interactive outdoor that gets in mechanical motion wih every coin you donate. Not only that, it educates about the final destination of your contributions. You also score social points, as it takes a photo of you and posts it to Facebook.
You just want to see the journey of the coin again and again. As I said, ingenius!
