Hold shift and click on green flag to start. Shift+green flag activates turbo (quick) mode. Than click one more time on the green flag. As soon as you do this you will see three rotating dots (if they appear not to be moving, then try again shift+green flag), where only green dot actually draws. It takes some time to draw this shape to the end. Each shape is drawn to the end when green dot reaches starting point and starts repeating already drawn lines. Blue dot is rotating around the center of the canvas, red dot rotates around the blue dot and green dot is rotating around the red dot. Even slight change of the rotating speed (change of +-1) of any of these dots will result in another shape being drawn. By clicking on colored dots in the lower right corner you can change direction of rotation of dots. This will also produce different image. Try first always simple ratios, like: 10:20:30, 15:25:75, 30:60:90,...Simple ratios produce image in very short time, but there are many other as well. It just takes bit longer. Also try to keep good simple ratio and only change rotation direction. Change parameters before you click on 'start drawing' button and wait for result. If you change some of parameters during the drawing process it is very likely that this will produce messy results (if you don't wait until full image is done). Have a fun!
Please report bugs. Remix idea: set y of blue dot to 0. This will make blue dot slide horizontally and produce different set of images.
