The CityWall is a large multi-touch display in Helsinki Finland which acts as a collaborative and playful interface for the ever-changing media landscape of the city.

Public content from Flickr and Youtube feed the wall with pictures and videos. Citizens can even contribute to the wall by sending an email or an MMS to post@citywall.org. Alternatively, tag your media on YouTube and Flickr with “Helsinki” and it’ll automatically be picked up. Users navigate the content by touchscreen. Check out the video.
