Dam Square, Amsterdam, saturday 24th of April 14:00h there will be an "Augmented Reality Flash mob". All you need to do is prep your phone with the right AR software, and show up - there will be AR tags on the ground ready for the magic to happen.

Every square in every major city in the world knows the 'human statue' phenomenon. On the Dam square in Amsterdam we've the following set of characters: a Darth Vader, a superman, a gladiator and some undecipherable sort of gothic characters.
Even though they have nothing to do with the city of Amsterdam, people go and have their picture taken with them on and off.
But not on the 24th of April! Then, the majority of people will be photographing the empty space beside Darth. Because that space will be occupied by virtual 'human sculptures', brought alive by Augmented Reality applications on iPhones and Android devices!
