Look at the code to see how this pattern was created and make variations to see other patterns. Look at Selim´s original project too! This is the second one I´ve made for LCL2020.
I´ve had a lot of (hard) fun when, thinking about maths or remixing with Scratch, I´ve asked myself "What if . . . ?" Greetings and lots of thanks to Selim =)
