Fresh out of university in 2009 I worked as a graphic designer at a tiny UX/UI studio (4 including myself) that did contract work primarily for RIM (Blackberry). A year into this job, the founder surprised me with announcing that we would do a 2-week creative exploration (what I'd now call a hackathon)— everything else was put on hold completely. A ton of ideas (and fun) were had. We ended up shipping two iOS games over the next 6-12mo... that, frankly, didn't amount to much (in hindsight, how could it— we were all kids (<24yrs old) with 0 experience in games).

It was strange, interesting and amazing time.
