Click the green flag, sit back, enjoy. Change the slider and click the green flag again to see a different pattern. (The slider value is the angle the sprite turns before creating the next clone.) Try 59, 60 and 61 and try to figure out why the patterns are so different. There are many other interesting angles :) Please check out the 100+ nice remixes made by other scratchers: https://scratch.mit.edu/studios/27457559/ And of course, feel free to remix yourself!
I changed a lot this time. Look inside.
