If you liked the video mapping on the IAC building, this one might be even better. For the 600th anniversary of the construction of the tower clock in Prague, The Macula projected a really great video on the tower...watch at least through the brick stacking animation.
This is one of my favorite photos:
It was taken by Josef Koudelka in Prague in 1968, just before the Soviet Union invaded and put a stop to The Prague Spring. To demonstrate the emptiness of the streets at noon, Koudelka stuck his wristwatch into the scene before shooting it. A simple, brilliant gesture that adds not only a temporal dimension to the photo but also a sense of solitary humanity in contrast to the empty streets.
