We’ve seen all sorts of displays over the years, many of which are iterations on old ideas. This clock, inspired by bicycle chain links, is unique. It’s not, as far as we know, based on anyone else’s work, and as such, it’s a huge leap forward in humankind’s ability to make cool things. Take a bow, Ekaggrat Singh Kalsi, Beijing-based architect and tinkerer and the creator of this prototype clock.

Each digit is its own self-contained module, and consists of a pair of stepper motors and two servos. The stepper motors push the chain up out of the base of the assembly, and the servos bend each link of the chain enough to form the shape of the number. It’s a fascinating idea and, for such a mechanically inspired display, it’s surprisingly organic to watch.
