Just a simple Pen animation. Also, my 1000th shared project, although I didn't realize it when I shared it.
Thanks to @TanSinCos for the idea: https://scratch.mit.edu/projects/960576158/#comments-382494844 I didn't use @TanSinCos' project as a reference, but it was mentioned in the comment that inspired me to make this, so please check it out: https://scratch.mit.edu/projects/810079961/
