3D porn, 3D doc, IMAX stuff, Space/NASA stuff, Science stuff, Animals/Insects/Bugs, 3D TV show, 3D dancing, 3D sports, most likely the London Olympics too - if you know where to find them, they are available.
Since there is no more significant premium to buying 3D functionality (because what you get nowadays is primarily a very good quality 2D TV), it's cool to have.
