phenakistoscopic

— A modified form of the phenakistoscope, in which the usual figures of horsemen, &c., are replaced in the revolving disk by a double set of highly-coloured circular arcs, all passing through the centre of motion, and intersecting each other, pair and pair, in such a way that the limbs exhibit a slightly different relation in each successive pair, on the same principle as ordinary phenakistoscopic figures are arranged.
