EXCLUSIVE! A kinegram is the appearance of movement on a stagnant graphic image-this effect produces the illusion of animation! A perforated overlay turns independently of the clock base, making a mesmerizing illusion of a playful cat with every passing second! Requires one D battery for the sound and 3 AA batteries for the clock (not included). On/ off button located on the back for sound effect on every hour. Instructions included. Plastic and aluminum. 12"x 2"
