I strived to make a clean and truly random mixed messages project.
I used an SQLite database to store the previously displayed message so that the user would ALWAYS received a new quote. On top of that, I used a JSON to store the messages so that adding/editing/deleting new quotes/messages was easy.
Some feedback regarding this project would be awesome! This took me around 1 hour to plan, create and test.
Feel free to use code or adapt the project to your own idea.
