I'll never forget this project a friend and I worked on because of the "clear your devices" procedure they had us do before every test to make sure we weren't cheating or something. At that point we could archive things and whatnot, but it was just a PITA to deal with it and we kept getting annoyed at having to clear our calculators. So then, of course, we made our own program that would simulate the memory cleared screen, and we used it successfully. Of course, we got paranoid lest anyone would find out, so we ended up just adding to it, so you could then interact with the calculator and even do math on it, so it wouldn't seem like you were interacting with our program. Funnily enough neither of us ever came close to using it for cheating -- I mean, we didn't need it. But I maintain that in the couple decades since, it was probably some of my best work.
