Nørd Camp (“Geek Camp” in Danish) is a project of the Roskilde Festival in Denmark. In poorly-translated-from-Danish it describes itself as a summer camp where:

Every day is a new day filled with new challenges, tasks and not the least knowledge of the real Big Nerd spirit. Participants are involved in building projects, shaping them and test whether they work in the end. This will bring participants through many different things — everything from chemical reactions to build soapbox cars and final competition.

In short, it looks like the greatest camp on earth.
