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.

No not the popos, but the other display technology challenging OLEDs, SEDs and backlight LCDs for flat screen supremacy. Sony recently demonstrated their FED (field emission display) TV designed for high-end graphics and broadcast use.

The 19.2″ FED panel has a 1,280 x 960 pixel resolution with a contrast ratio of 20,000:1. As constrasty as that sounds don’t expect any FEDs to show up before 2009 and if they do, they could be the wrong kind. You know, the kind that are handcuff happy.

BTW, does anyone else think his metallic jacket is just precious?
