This years Magneet Festival, the first crowdsourced festival of its kind in Europe, is taking place on an artificial sand valley at the Zeeburger Island (Zeeburgereiland) in the East of Amsterdam. Visitors can enjoy music, theatre, experimental constructions, fine arts, childrens activities and more. My friends have built a nomadic house called the Mobi-01 which will be on site for the duration of the month-long festival. For more information about the Mobi-01 see
