Double-click green flag. Not really anything interesting, just testing out clone id management. Takes a second to load, cause it has to create 240 clones, angle them 1.5 degrees apart, and assign them all an individual id.
Update: June 1st, 2023: Made more accurate with 240 clones instead of 180. Takes even longer to load now :) about 30 seconds. Update: April 30th, 2023; Added the option to change the size-changing attribute and direction. Press the space key to change direction, use the up and down arrows to change the size-changing rate. Can create some pretty interesting patterns, showing just how complex something as simple as rectangles going in different directions can be.
