This piece was originally created as a research project to see if it was possible to create a back screen in Scratch. After making it, I found that although the FPS drops to less than half, it is not unfeasible. I don't know what it can be used for, but I believe it will improve the technology on Scratch. My thought is that it will probably make applying textures easier. What I have created is the presence of a back screen, and the screen is immediately drawn. Please make your own modifications to those areas and create your own work.
