Some time ago we went to a historic festival. We saw a really impressive re-enactment of a battle in the eighty years' war. It really gives you a better impression of how warfare went one back then. At the same time I felt slightly uncomfortable seeing people playing war, when there are so many real wars going on not so far away. At least we got to explain more about that war and local history to the kids. One of the pictures I used to try the new app Circular (similar for android: Spherify). Very funny and beautiful results.
