In the classic MacOS days you could use the included Script Editor to record your interactions with applications like the Finder, generating AppleScript to replay the actions you took like resizing windows or creating new folders on the desktop. Then you could have fun making some procedural art wrapping the code in "repeat 100 times ... end repeat". Your parents would really love how you rearranged their documents.
Script Editor still exists in modern macOS but sadly Apple never made the Record feature work particularly well on Mac OS X and hardly any developers prioritize AppleEvent support.
