Here is this wonderful stuff I found for you, its a clock which writes time on a board with its mechanical hands, and then it wipes of time and then write again the current time. Do not believe, see the video below.
It is known as Plotclock and is made up of 3D printed parts and mechanisms, connected by M3 nuts, bolts and thread tape.
It is powered by an Arduino Uno board and three servos control and manage the movement of its arms.

Surely it is a treat to watch and would be a fun way to have a clock on your table.
