This seems to have spread all over the design and architecture blogs. Cloud by Troika is a beautiful object and really superb piece of engineering, especially with its mix of high tech digital control and nostalgic low tech actuation.

There’s a nice video here from youtube and Chris O’Shea has some details on pixelsumo blog which includes some behind the scenes images of the custom software used on the project.

my thanks to Eva Rucki of Troika for the tip
