A clock with only hands and no dial

Of course, a clock without scales is neither strange nor novel, because liquid crystal display electronic watches don't have scales. But this is a clock with minute and hour hands that rotate. It's novel in that it has no scale or reference at all.

However, the tips of the minute and hour hands of this clock are LED screens. No matter where the hands rotate to, the screen at the top will real-timely display the time scale corresponding to this position. Isn't this an interesting design?
