Mathematical Shapes Created with String by Jean Rintoul

The images above consist of a cardioid, an astroid, and a squircle (yes, that is a real shape), all created using string.

String art, or pin and thread art, is characterized by an arrangement of colored thread strung between points to form abstract geometric patterns or representational designs such as a ship’s sails, sometimes with other artist material comprising the remainder of the work. Thread, wire, or string is wound around a grid of nails hammered into a velvet-covered wooden board. Though straight lines are formed by the string, the slightly different angles and metric positions at which strings intersect may give the appearance of Bézier curves (and often construct good approximations of quadratic Bézier curves).

String art has its origins in the ‘curve stitch’ activities invented by Mary Everest Boole at the end of the 19th Century to make mathematical ideas more accessible to children.
