THIS PROJECT ONLY WORKS IN FULLSCREEN!!! Hold space to see a more refined area around your mouse! Hold down your mouse to freeze to a single frame!
It works by taking a bitmap sprite (shown on the left and dithering it. you overlay the two dithered sprites on top of each other, and then size it down to 50%. and all of a sudden, you have clip zones! Keep in mind that these clip lines are only where scratch put them, but it's a start! Ask in the comments if you want a more refined explanation!
