During my first hackathon I teamed up with some strangers. We decided to create some games by expanding reality with virtual element (sounds mysteriously and maybe even ominously, but it's not). So here we go - one of them started building android app, the second guy started building window app in C++ and the last one of them decided to create something in JavaScript. It was fun, but I wasn't prepared and so much educated, so after some trials that ended poorly, the only thing I did was the wooden construction that was supposed to hold our tablet up so it could shoot photos recursively. I almost died of boredom for the remaining time.
