I recently discovered MasterClass.com. They have online classes by some of the world's top chefs, eg Thomas Keller, Wolfgang Puck, as well as a variety of courses for creative types (writing, acting, music, etc). They seem to be successful at attracting the "best in the world" in various professions to run the courses. You can buy courses individually or get an annual open access to all courses. I've done some of their culinary ones and found them interesting. They're not just cooking lessons but also the chefs talking about their journeys and culinary philosophies with a lot of hints and tips thrown in. It's an interesting way to spend an afternoon or two and makes a change from reading cookbooks or biographies.
