I hope you understand this compiliation is far from finished. Those are the sites I had on top of my head; please correct me or suggest other/better sites. This is a work in progress, of course. =)
-Edit #1 - Added three videos.
-Edit #2 - Updated the thread a bit with new links to sites rather than specific links, to give the links a longer lifespan and to link to recent and updated information.
