We held our QR-code against an electronic eye to make a photo. The results were put on a website of the museum you could watch at home. As you can see the photos are rather hilarious, everybody is only seen in a corner of the photo, without the harnas.
In fact this had to be the result. SC made this photo of me in the harnas, trying to use my QR-code. He was so "interactive" that even this one is blurry. Well we had a lot of fun.
