A presentation for the Inspiration Seminar on Digital Communications and Heritage (Inspirationsseminarium Digital kommunikation & kulturarv, #kulturwebb) at the Nordic Museum, organised by the Nordic Museum's New Media department in collaboration with Mabb and IdeK lab.
I've saved my slides and speaker notes as a PDF (7mb): Museum Crowdsourcing Games: Improving Collections Through Play (and some thoughts on the future of museums) and the video is at http://bambuser.com/channel/nordiskamuseet/broadcast/1646762 (though I'm not sure how long it'll be there).
