ZuriHac was a three-day-long hackathon for Haskell programmers who traveled to Zurich, Switzerland from all over Europe and the Northern Hemisphere. The event was held at the Google office, and they are apparently very paranoid, so I didn't get to take any pictures inside the building. David Anderson has fortunately provided Google-approved inside-ZuriHac photos. I offer a complementary set of "outside" photos.
Note: I would like to have everybody's name here. If you see your picture and want your name associated with it, please leave a comment or send me an email.
