Phénakisticope Spinner Set: two spinners- one a laser cut and printed acrylic with a set of images similar to the animation design of a flip book (but in a repeating cycle)- and the second a black disk with thin slit openings. Spin them in opposite directions and then look through the black disk at the first to reveal an animated image, in this case a running stick person. The effect looks better in person in that the frame rate of the video capture process adds some artifacts. Using the second black disk like this turns the spinners into a phenakistiscope, the 1833 invention that started moving media animation that lead to the development of movies and video. Under very bright light the animation can also be seen using a smartphone camera in video mode, but the black disk allows one to see the animation without such technology.
