We've been talking about it for some time, but recently the first semi-functioning prototypes of a digital ring-clock capable of communicating with devices have emerged.

The system is equipped with a wireless rechargeable lithium battery, which provides a full week of use on a single charge.
Here is another couple of videos that show the progress of the prototype and the various stages of processing.
