I have been going through my notebook and found ideas for software I had noted down. Here are some you can have for free:
Text editor that exits and deletes the file if you make an error.
File browser that only allows you to open 10 files a day.
An OS that will allow you to run 10000 commands, as soon as the 10000th command finishes it erases the drive it’s on completely.
An image editor that will only open images of boats.
Calculator that gives the answers to the previous sum
That first one runs the risk of being actually useful
@jameschip Some of your ideas remind me a lot of Agrippa, an ancient Mac app that displayed a story onscreen and encrypted it afterwards:
Revel in the marvels of the universe. We are a collective of forward-thinking individuals who strive to better ourselves and our surroundings through constant creation. We express ourselves through music, art, games, and writing. We also put great value in play. A warm welcome to any like-minded people who feel these ideals resonate with them.
