Here you can find my slides presented 2 days ago at Wordcamp Bulgaria. You will definitely need Firefox 4 beta 2 at least because my slides are based on DZslides, published by Paul Rouget and modified by me.
There is very funny video in there and you can learn Bulgarian while trying to understand what I am talking about :)
The good news is I was invited to WordCamp Romania and I will be presenting the same topic with the same technologies. I love OpenWeb and Open Technologies :)
