Visitors of the  E-Culturefair in Dortmund  23-25 aug were be able to (re)shape the city's appearance.. An augmented reality building toolkit (built with  Layar ) for iPhone and Android phones turned the whole city into one big virtual construction site.

By walking on the streets of Dortmund, people using Layar on their mobile phone people could place virtual blocks, or pile blocks on top of each other, thereby creating shapes as big or bigger as the nearby buildings, such as the iconic Dortmunder U-turm. "The sky is not the limit!"

Cityshapes is a new project in a series of experiments bridging the virtual space and the real space, developed by  Sander Veenhof
