This project demonstrates how Scratch can be used to create real files. In this case, you draw a design on the grid, hit export, and it creates a .bmp file for you. To actually see your bitmap outside of Scratch: 1. Create a new file on your computer with a .bmp extension 2. Open the file with any hex editor that supports pasting 3. Paste the export data right into the file and save 4. Now you can open your bitmap!
