Click to zoom in Don't forget to run in turbo mode to make it faster! (Shift + click the green flag) This is the famous Mandelbrot set, represented graphically in scratch. Space to zoom out, or press start again to zoom back to the beginning. Press R to redraw without changing the zoom. (If clicking doesn't always work to zoom it in, try holding the mouse down for just a second every time you click)
The program will make the picture more accurate as fast as it can, but you'll have to wait a bit to get a higher definition image. You can still change the zoom while it's drawing without issue. It's a fractal, so you can keep zooming as long as Scratch's variables have memory! Feel free to comment the coordinates of any cool spots you find.
