I remember way back in uni at a hackathon, our table had a projector on it so of course we connected to it and set up Hacker Typer to auto play and keep typing out gibberish. But then some sponsor walked on by and stared, visibly impressed by what was happening. It wasn’t until they asked for a picture that we realized they had never seen Hacker Typer before. And yes, we took the picture without telling them what it was.
