The following pictures show the tube spinning.
Of course, only one of the cathodes is glowing, but the shutter speed of the
camera generates different pictures:
A normal shutter speed of the camera:
A high shutter speed of the camera:
A low shutter speed of the camera:
By night, with low shutter speed of the camera:
