The main Twitch homepage will now include a tab labeled Creative. This will link to an entire homepage dedicated to Twitch Creative that will feature the most popular streams and up-and-coming broadcasters. It will feature painters, sculptors, and musicians live streaming their work as it happens, instead of simply sharing the finished piece. And in the spirit of the form, Twitch will be live streaming all 403 episodes of The Joy of Painting, the seminal Bob Ross program that many Twitch creators credit as an inspiration.
