There's a surprising amount in the multiple floors here, I was particularly interested in how the concepts of illusions date back so far. Big kid and little kids will love it, there's something here for all ages. The camera obscura itself is fantastic and the time we spent playing with the zooming cameras on the rooftops are a sobering reminder of just what can be seen from a distance. At one point we were virtually reading someone's phone messages from afar!
