This is a 240x135 resolution pixel display, built in Scratch! It uses subpixels like a real TV or monitor would, so if you look close (not too close on this small resolution) you can see the individual red, green, and blue subpixels! It renders images fully natively in Scratch, and if you want to import your own images, go to the notes and credits. Let me know if anything doesn't work correctly with the importing process, and hopefully I can help you fix it. v2: the image takes up the whole screen (except the black bars at the top/bottom because Scratch is 4:3) Yes, that is the globglogabgalab.
Steps to import a custom image: 1. download a picture you want to use (preferably at 16:9 aspect ratio, which is most commonly 1280x720, 1920x1080, 2560x1440, or 3840x2160.) 2. resize the image (I use imageresizer.com) to 240x135 resolution, then download the resized one. 3. go to https://xeltalliv.github.io/ScratchTools/Img2list/#dn1 and select "decimal new line RGB" in the "mode" dropdown, upload your RESIZED image, then it will download a .txt file (you can delete all the images from before now) 4. go inside this project and press "c", after the green flag is pressed, then the list will show, right click anywhere in the list on the stage, then press import, select your .txt file, click the green flag again then it should render on the screen!
