An optical device, in which a series of animated sequences of unlimited length is viewed, includes a stationary cylindrical drum 1 with a vertical opening 4 and equidistant slots 2 and a rotating cylindrical shutter drum 9 with corresponding slots. A crank handle 15 connected to pulleys imparts rotational motion to the drum 9 causing a picture band 3 fed from spool 5 to advance in the space between the drums by the action of the struts 13 on drum 9 upon the studs 21 on the picture band, while simultaneously opening and closing the view of the band through slots. Thus viewers looking at the picture band through the slots 2 observe an animated display of a non-repetitive nature and of a longer length unlike the traditional zoetrope. |
