I gave an HTML5 presentation at Fronteers 2008 with some special focus to the video element. Great fun. Using an Opera Labs build I included a video element in the presentation itself. (My presentations are typically done in HTML5, presented using Opera in fullscreen mode.) The presentation: Fronteers 2008 — HTML5.
I enjoyed the presentation. Your enthusiasm does the trick! Also nice to see GNU/Linux being used within the web development scene.
My highlight of the conference: Anne, in a Q42 shirt, signing up for Fronteers ;) Yay! Hoi Anne!
