Timekeeping has always fascinated me, as has the difference between appearance and substance (especially in connection with machines that may seem sentient, for example).
Today’s invention is a novel clock display. A conventional clockwork mechanism consists of a spring driving a single spindle via a ratchet. Protruding radially from the spindle are images of the face of a real clock -one image per minute.
As the ratchet operates, so a new picture is flicked into place every minute -just as in a circular flickbook or zoetrope. This allows one to have any clock face on the timepiece, from a hand-drawn one to photographs of Westminster clock tower taken one per minute.
