Click the green flag to start browsing through the collection of drawings; each time starting from a different (randomly chosen) point. Seen a drawing you like? Press space or click the stage to stop the flow; use the left arrow to step back if necessary. Take note of the ID in the bottom left corner; you can always return to a particular drawing using button 'Go to ID' (or 'G' on keyboard; first letter works on any button). Press space again to resume browsing. Alternatively, hold down the mouse button for one second on a green arrow; this works in both directions. Click button 'Script' to generate a Scratch script; this should help you reproduce the drawing in a project of your own. Try make it an entry for the 15 Word Challenge; please make sure you read the challenge rules before you do. https://scratch.mit.edu/studios/3693249/
Please feel free to post the ID of your favorite mandala. Example: 61:0:48 (the one in the title screen). Or even better, make it a project and submit it to the 15 Word Challenge! See instructions above for details. This project is one giant collection of mandalas (in the popular sense, not as spiritual symbols). Total number of drawings: 128,880. If your hardware is fast enough to show 10 drawings per second, then you can watch the entire collection in 3 hours 35 minutes. :-P ALGORITHM Every drawing is made by a simple 'move & turn' loop. Move distance is fixed, turning angle is a quadratic function of the loop count. It's the coefficients that make each drawing unique (a, b, c in the quadratic function a*x*(x+b) + c). This project only explores (part of) the integer coefficients; you may want to try fractional numbers to get even more complex patterns. HISTORY This project started as a really simple random generator to explore cool patterns for @Scratch-Minion's 15 Word Challenge. https://scratch.mit.edu/studios/3693249/ That's how I found the 'Twelve Little Lions' (1:0:358) and the main image of the Dutch Wiki Wednesday article (1:0:359). http://nl.scratch-wiki.info/wiki/Pen-kunst_tekenen Making the patterns fit the stage used to be tedious work (center and scale; varies greatly between drawings), so I automated that. The result looked so good that I decided to share the project (after adding some more enhancements like navigation buttons and the 'script' feature). BUGS Some patterns are not arched (e.g. 3:1:4); the result of making it fit the stage is often little more than a straight line. On slow hardware, speed 4 is already the fastest possible; there will be no noticeable difference when increasing speed to 5.
