What do you get when you combine a 1:1000-scale model of Tokyo, 3D video projection mapping and catchy techno riffs? Three minutes of awesome, that's what.

To celebrate the ten year anniversary of its opening, the Roppongi Hills complex (part high-rise residences, part shopping district, part entertainment venue) created this wicked cool short, Tokyo City Symphony. By projecting 3D animation onto a 1:1000-scale model of the capital city, the video's producers were able to make the cityscape appear to dance along to the music.

What's more, you can generate your own 12-bar mix and share it on the Tokyo City Symphony website, adding it to a growing communal stream of user-created riffs. But why, oh why, didn't they include the ability to export your track to a ringtone? [Tokyo City Symphony]
