'Geek Glastonbury': Milton Keynes hosts technology campsite
7 September 2012 Last updated at 09:19 BST
At first glance, it looks like a typical summer festival at Pineham Park, Milton Keynes - a haphazard collection of tents, portable toilets and a very well-stocked bar.
But not every festival has its own bespoke 300 megabits per second (Mbps) broadband connection, electricity almost literally on tap thanks to networks of specially adapted outdoor toilets called Datenklos, and delegate badges that change colour according to who you are meeting (developed in collaboration with University College London).
The very first Electromagnetic Field Festival, known as EMF, started at Pineham Park in Milton Keynes on Friday and runs until 2 September.
One of the organisers, Jonty Wareing, offered the BBC a behind-the-scenes tour.
