Use the mouse (click and drag) to draw, and press space to clear the screen. This project could have gone on @PullJosh_test, but I thought it was an interesting enough idea to be worth sharing here. Essentially, the project helps you draw with smooth lines rather than rigid ones. The light gray line shows a regular pen drawing as compared to the smoother blue one.
I found the smooth angle turning script in my backpack. I remember grabbing it from someone, but I can't remember who.
