Mid-May is the of year when Northern hemisphere students are supposed to be studying for their exams.

Take the kids at the Polish Wroclaw University of Technology, for instance, who recently refashioned their dorm into a massive 12x10 display, complete with a psychedelic (and slightly too long) light show. Take a look below, and don't be surprised if you see these kids applying to retake their finals next summer.
