Kinegram
A kinegram is an animation medium. Visual artist Gianni A. Sarcone describes them as using elements of the Moiré pattern and the zoetrope (one of the precursors of film animation). The resulting animated sequence appears similar to that of the zoetrope by producing an illusion of movement. It works by placing an acetate overlay containing vertical stripes over a specially prepared image and slowly moved from right to left.
The concept has been adapted commercially. One such brand, "Scanimation," publishes book sets and greeting cards. This adaptation was developed by Rufus Butler Seder, who is listed as inventor on a 2006 United States patent.
