One of my favorite hackathon projects was using an unofficial Robinhood API (<a href="https://github.com/sanko/Robinhood" rel="nofollow">https://github.com/sanko/Robinhood</a>) to ask Alexa how a current stock was doing. If it had increased over the last year, I would ask Alexa to "purchase X shares of X stock".<p>Writing joke apps is a fun way to try out a new programming language and laugh about it.
