This is 2D Painter, a project you can use to draw things with the ball! The ball will keep on going to the mouse-pointer. If you click on the ball, the pen will go down for 2.1 seconds. Then, the pen will go up again. The different colours are on the side. The letter is written in the colour the letter represents. For example, if you press A key, the colour will change to red. If you don't want the colours avalible, you can click "More Colours". Then you would have to type the colour, transparency, saturation and brightness. 2D Painter automatically saves your work if you stay in the website. To clear screen, click space key. It cannot save your work if you leave the website.
It didn't take me long - it took me about an hour and was pretty easy. A 2D Painter Version is available on Apptop 2000. Link: https://scratch.mit.edu/projects/628284126/ Hope you enjoy!
