In the early 2000's, I created TI-83+ applications for solving various introductory physics homework problems — and copied to a few friends' calculators. Ten years later, a friend's little brother randomly quipped "thanks for doing all my physics homework!"
When I saw my own little brother next holiday, he confirmed that his entire physics class had utilized my problem solvers, and most had also played my TI-83+ version of Blackjack.
