We will start the each day with an empty grid. We will have rooms, we will have timeslots, we will have you as participants. We will introduce the concept, warm you up with one or two short talks to get you inspired, and then leave it up to you to claim a slot and make the conference happen. You can be prepared or unprepared, it doesn’t matter. There is a timeslot and a room for you, and if you present something interesting, you will have an audience to share it with. And as it is your unconference, anything goes, as long as it is somehow related to space.
