HTML5TV: video archive with slide sync without plugins

Last weekend we had Nothing will happen event and I did small presentation about HTML5TV which is:

• video annotation interface based on mplayer with slide overview
• web interface using HTML5 <video> tag and some JavaScript

I have collected some of presentations at http://html5tv.rot13.org/, so hop over there and have a look. If you have more interesting presentations, you can easily fork HTML5TV at github, annotate presentation and submit it for inclusion (or make your own archive if you prefer that). Have fun and let me know what you think about it.
