There's poor video quality (google video), but the content was worth the watch, imo. I'd never been that interested in the Mayan Calendar before, mostly because it seemed too convoluted to bother, but this presentation created a shift in my ability to perceive and comprehend it. Pretty cool.

EDIT: I should add that it's not nearly just about a calendar, btw, but talks about consciousness, time, evolution and what's on the horizon for us all as consciousness shifts its focus, time appears to speed up, and the mind can't keep up. And more.
