This project uses the Pen extension to generate shapes. It also has a unique little feature where the more the pen shape, the bigger it draws it.
Recommended for generating circles a size of 5-32. Lesser than 5 will give incomplete circles, and over 32 will start generating scribblish-like shapes. For squares, recommended 1-7. This project is NOT stolen, I was just doing some simple stuff. Sorry if the sizes are too compressed, Scratch is very limited.
