You can peer at the bearded fellow in the presentation abstract here (I'll talk about the dojox.gfx and dojox.charting cross-browser graphics packages); http://jsconf.eu/2009/speaker/peter_svensson_-_using_dojoxgf.html but just in case, the text is copied below;
Peter Svensson will give us deep insights into real-time 2D graphics in the browser.
He is a contributor to the Dojo Ajax Toolkit and author of the book "Learning Dojo". When not talking at conferences, he's busy developing his company "Hermit Village" with competences ranging from Dojo, Android, and App Engine to OpenSocial, Layar and Google Friend Connect. He is also the organizer of the Scandinavian Web Developer Conferences and the Google Technology User Group for Stockholm, Sweden.
What? There was an equally Epic Google technology User Group - Stockholm meeting last night, with over 90 people present. True, but this has been a hectic week and I really need to sleep first before attempting that post. Coming during the weekend though. Films at eleven. beep.
