This is a gewgaw from circa May 2016, where a curve is randomly drawn using semicircles.

The first implementation of Semicircle Jam (which we will call version 1.0) was located in the HTML5 Gewgaws distribution. The current version found in this repository (which we will call version 1.1 or later) has had several improvements made to it:

• It has been adapted to use DAM.
• It now has controls to restart, continue, and close the loop off.
• "pinches" in the curve are no longer generated.
• By default, "slots" are exclusive: no position along the spine of the curve is re-used during a single generation phase.
• By default, the loop is automatically closed off at the end of the generation phase.
