07/04/2021 - Finally updated for Scratch 3! I figured that this was getting so many views it would be worth it :P This is a cool little project to simulate the lock screen on some android phones. The idea came to me a while ago, and now I've finally put it into action! To draw a pattern, click and hold one of the dots in the grid, then move your mouse around to other dots to create a pattern. Let go of the mouse button to finish. When you set your unlock pattern, try to remember it so you can get it correct next time! To change your pattern, click 'Change Pattern' at the top.
