Btw Pixel image generator 2 is better than this: https://scratch.mit.edu/projects/706617423/ Space to start (Pick an image at the bottom first). R to reset. It will take a long time to "print" the selected image, so i recommend using turbowarp (The link is with 250 fps for higher speed of "printing"): https://turbowarp.org/705489361?fps=250&hqpen You can choose if you want high quality pen on or off. The only difference is you want it to look like squares or circles.
There is a glitch where when you click on the black to white fade, and play it, and then when you go back to the rainbow or PCwwa OS 2 background, it will not print color. And there is a black stripe on the left of the PCwwa OS 2 background.
