Video clip of the world's first Nixie tube propeller clock (with soundtrack). Observe the light-bluish glow from the left side of the device [right side in the movie], as the camera's sensor picked up the otherwise invisible light from the infrared LED. Also, the choppiness in the display does not occur in real life; it is merely an artifact of the display refresh rate and video frame rate not being completely in sync. See more details at http://www.nixiana.com/hardware/ntpclock.shtml.
Thanks! :-) As a matter of fact, it is not unstable; see the explanation about the display's choppiness I just added to the description.
