I was taking a course on regex compiler design at Stanford long ago before they locked down their student access system. In that case they weren't meaning to share. Nice format though, video + coordinated slides in a two up view. Stanford iphone development and some Berkeley/Yale philosophy courses since then. Nothing yet from OCW.
I recently started to watch the iPhone Application Programming from Stanford (http://deimos3.apple.com/WebObjects/Core.woa/Browse/itunes.s...) and it is really great. For an introduction to Objective-C and iPhone development, so far it has been very, very well done. Most (if not all) speakers are actually Apple engineers.
That kind of initiatives is really great because honestly, Stanford can have a class given by Apple engineers pretty easily (in that they are very close by), but it would be quite difficult for any other college in the world, regardless of the quality of the school.
ECON 159 - Game Theory by Professor Ben Polak is very thorough.
Both are video-based, no materials required. Questionnaire pdfs between "classes" for recap.
