This high-tech wristwatch is more than a gyroscope in a globe. Besides always staying upright, the spinning clock face displays the time at the blink of an LED.
Actually there are three strobe LEDs in a pod, on an arm over the face. The clock hands are all really just one line on the face, spinning
at 60 revolutions per second. Since each LED has a different color, illumination diameter and blink times, the observers persistence of vision causes hour, minute and second hands to be seen.
By slowing the strobe of the second hand LED to just less than 60 flashes per second, the second hand appears to move smoothly, relative to the numbered, fixed outer ring. Being a gyroscope, means the watch can be read at almost any angle. Also a bubble watch on a chain and a gyro-watch ring are in development.

Analog/digital propellor clock, et al.
Same idea, less the gyroscope. These clocks work in analog or digital and can display text or images. [phoenix, Oct 04 2004, last modified Oct 21 2004]

||60 Hz is not enough for my eyes to overlook the flashing. So I, for one, will still see the flickering.
||I think I prefer the principle used in phoenix's first link. Just as half-baked, but potentially more compact.
||Rather more of a captivating feature, I guess.
||Oh crap, I croissanted this before it even hed an illustration. Could I please have another?
||It would be cool to make hubcaps that incorporate the
