Matryoshkas presents an animation composed of a infinite sequence of russian dolls. Each doll grows until revealing another doll inside it. To create the animation, we have used a threedimensional model of a doll, and deleted all its vertical edges and faces, preserving only its horizontal edges. As a result, we have dolls composed by horizontal circles, and an animation that can be considered a drawing. Over time, the color of the lines changes, creating “layers” of dolls in the background.
