Superposition is silly Mac app inspired by Schrödinger's cat. When you drag files on to the application it will create a password protected disk image the approximate size of your files. It will then either copy your files to the disk image or create an otherwise empty disk image with a readme text file that just says "The cat is dead."
Here is a video demonstration of the app: https://vimeo.com/858798755/ef81be0f23
This app was made with macOS Automator, and generous help from ChatGPT.
Files should first be placed in a single folder, and then that folder should be dragged on the Superposition app icon. This is due to this issue with Automator.
