Ok, the fun starts at 1:40 - the first 1:40 is a bit about the Jam - then it's an explaining of the Nordic Game Jam, this has now gone global, with more people than ever coming together to test ideas in a 48hour time frame :)

A bit about the Nordic Game Jam from the website
It is an event which aims to bring together artists, programmers and designers from the professional, amateur or student field, to spend a weekend working together in intense game development. The purpose is to give the developers an opportunity to work with other people than the usual, to show off their skills and creativity and to get respect for making great and innovative games in 49 hours. Nordic Game Jam '09 is the fourth annual game jam in Copenhagen and it will be held in the weekend between Jan 30 - Feb 1 2009. The event is non-profit and it is organized by the Danish chapter of International Game Developer's Association and the Center for Games Research at the IT-University.

This year for a first time the Nordic Game Jam is part of a Global Game Jam which means that all over the world there will be game jams that takes place in the same 48 hours. The Global Game Jam will start at 5:00PM Friday, January 30, 2009 through 3:00PM Sunday, February 1, 2009, (all times local). All participants in the Global Game Jam including the Nordic Game Jam will be constrained by the same rules and limitations, with each time zone having one distinct constraint.
