I didn't realize that the site could scroll and just closed it, until I saw your comment
Note it also scrolls down, I nearly missed half of the presentation at first, look for a green down arrow
I have to confess I found this the most confusing navigation interface ever. I quit after a half dozen slides. Was there a "home" option somewhere I stupidly missed?
Agree, cool presentation but I'd missed the down navigation until read these comments.
