Changing Milan

Well i read this post on a blog about how this person is talking about changing the Milan city. Milan already is a fashion capital of the world. They have the best and innovative technology. During the Universal Expo in 2015 in Milan, this project will be reviled in front of the world. One of the ideas which i found very appealing was to have nano technology on the walls of the building so that they can change color whenever and to whatever they want. The post contains many more ideas which will come true in 2015.
