Zeitgeist. Crazy shit. You MUST watch it.

Don't get all "shut up conspiracy nut" unless you watch the film.
Zeitgeist was created as a not for profit expression to inspire people to start looking at the world from a more critical perspective and to understand that very often things are not what the population at large think they are. The information in Zeitgeist was established over a year long period of research and the current Source page on this site lists the sources used / referenced. Soon, an interactive transcript will be online with detailed footnotes and links.
