This was a loading symbol when I was waiting for something to load on the computer and I was on the desktop. I was playing around with the little selection box (the box that appears when you drag your mouse on empty space on the desktop). I was dragging the mouse in a certain motion and it looked like this. I thought it looked cool so I made this.
Inside is the custom block that you can use with credit. Unfortunately, you will have to drag along the other custom blocks, so I'd advise copying the whole sprite into your backpack. Here's another pen loading symbol project by me: https://scratch.mit.edu/projects/73323126/
