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.

A plotter apparatus inscribes a polygon in a circle, and includes a ruler body, a first slider, a second slider, multiple brachiums, and a nib member. The ruler body comprises a knap, and a first ruler groove and a second ruler groove to allow movement of the first slider and the second slider. The brachiums are connected across the ruler body via pivots. The nib member allows the drawing of the circle. A fourth brachium is attached to a predetermined numbered hole on a second and a third brachium as per the number of sides required on the polygon. The length of each side of the polygon is retrieved between the knap and a slider. Cyclic arcs, with the determined length as a length of one side of the polygon, are drawn along the circumference of the circle. The arc intersections on the circle are joined together to define the polygon.

An art medium applicator includes a rotating shaft and an art medium coupled thereto for causing the medium to travel through an application path for transfer to a substrate. The applicator includes a coupling assembly, and may include an applicator tip including a cavity into which the art medium is inserted and supported. An art medium modifier includes a rotating shaft and an art medium modifier coupled thereto for causing the modifier to travel through an application path for modification of an art medium previously applied to a substrate.

A fourth brachium is attached to a pre-determined numbered hole on a second and a third brachium as per the number of sides required on the polygon. The length of each side of the polygon is retrieved between the knap and a slider. Cyclic arcs, with the determined length as a length of one side of the polygon, are drawn along the circumference of the circle.
