Unfortunately I have no information on this really cool clock, found on Design Llama.
Thanks to my buddy Adrian White the mystery is solved!
This striking clock, with copper digits mounted onto a bicycle chain to place emphasis on the cyclical nature of time, is the Catena Clock by Andreas Dober of the Anthologie Quartett.
I really like this too, but one thing that niggles with me is that it looks like it’s running backwards so that the 11 is followed by 10 and so on. I can see the logic for it running in the direction it is at the moment, but to me it just doesn’t *feel* right.
