If you’re in Helsinki, you want to check out CityWall at the corner of Lasipalatsi (map). I took some pics in Helsinki, then went home to upload them to Flickr. When I came back a couple hours later I walked past the CityWall and saw my pictures there. That was pretty awesome! The CityWall automatically fetches pictures from Flickr that are tagged “Helsinki”. Kind of neat, you can watch in close to real time what’s happening in the city. For mobile users it works even better. The user interface is like something from Minority Report, it’s something you’ve never seen before but you know straight away how to use it. You can rotate and stretch pictures, you can zoom into the timeline and throw the pictures around… I saw a couple of little kids try it out – even the kids knew immediately how to use it! This is really the user interface of the future, the most intuitive thing I have ever seen. Cooler than the iPhone. Really awesome. Jeff Han has demonstrated this kind of technology earlier, but this wall is the first public multi-touch interface of this scale in the world. Just come to Helsinki if you want to play with it 
If you don’t believe me, check out this video. Oh and they interviewed me about my experience. I hope I managed to say something sensible.
