Slides in PDF and
Keynote. If you want to extract the equations
from the slides you can do so by using LaTeXit, simply by dragging the
equation images into it.
Scribe's notes will be available once they're ready.
The quality is rather rough (this is unedited video straight from a
Lumix GF2 with a 14mm lens which should explain the sound and the
exaggerated hands). But it should help as a supplement with the slides.
