Interesting activation stunt by McCann, Oslo for Windows 8 for one of its key innovations; Live Tiles. They placed a Music branded tile on a street, when people stood on the tile it let down the walls of a fake house, and showed a famous Norwegian band playing inside.
Although this looks incredibly staged, (I can’t imagine anyone taking the chance of dropping a large wall around the general public) it does show the function of the preview tile in an enjoyable way.
If you are yet to try Windows 8 I urge you to have a go, I have been using it now for a couple of weeks and it’s incredible. To learn more about Windows 8 and Live Tiles go to http://windows.microsoft.com/en-us/windows-8/meet
