click the green flag and watch the spiral spin. if you want to change the spiral a bit, use the slider variables to change the angle, the speed, and the size of the pen. I set the variables to 3, 4, 0 and 0. Press the space key to clear the pen. You can even make mosaics from this project!
I used some ideas from a book that I have. I made this by a ball sprite. I also made this by understanding cloning (to clone the ball sprite) and the "pen" blocks (because I'm new to Scratch). If you drag the sliders to their limits: CRAZYYYYYYYY!!!!!.
