Easy Pen Art 1 (Rolling Rectangles) - Click Flag to Run Turn Turbo Mode on (Shift-Green Flag - also turns it off when it's on) to get to the final result quickly.
Created by @gregatku for use in Coding Classes for Kids Unlimited, for whom I work as a Coding teacher. Sample project to show kids how, by repetitively making minor changes to a few drawing parameters, like pen-size, colour, line length or turn angle, some interesting Pen Art can be created. We want kids to use these and other ideas they can find by looking in the Spiral Art Studio or searching for other "Pen Art", to come up with their own unique and creative pieces of Pen Art.
