Abstract
The technology described herein relates to a spiral art device that allows a user to create and recreate spiral art designs with chalk, and in particular with sidewalk chalk. The spiral art device in accordance with aspects herein comprises one or more stencil pieces and a motor piece. The motor piece is configured to move the stencil piece a predetermined distance around the motor piece, as many times as desired to form the spiral art design. The stencil piece is configured to have multiple securing points that allow the stencil piece to be secured to the motor piece at different angles, further allowing the user to add additional variations to their spiral art design. Design variations may be exponentially multiplied when multiple stencils having differently shaped traceable margins are provided with the spiral art device in accordance with aspects herein.
