I attended a few more presentations on the CSS power at the camp:
Shkrubbel, using web technologies to build a multi-player word game, by Kitt Hodsden. Kitt is a vivacious speaker.
The Future of CSS - Current Experiments and Near-Future Reality, by Tab Atkins. Tab has advanced knowledge of what is happening in the W3C CSS community, because he is a member of the W3C CSS Working Group, among others, while being a software engineer at Google.
Open Web Camp attracts a good community of web developers, thanks to its sponsors for free admission.
