Minnetrista in Muncie Indiana is looking to revive the former WIPB studio where Bob Ross filmed every episode of The Joy of Painting and turn it into a space for Bob Ross fans. They have started an IndieGoGo campaign with a $200k goal in order to restore the studio space, create a gallery for Bob's original work and create a workshop for fans to paint as well. Twitch, Hulu, WIPB and David Arquette (apparently he's a certified Bob Ross painting instructor?!) have already pledged money to the project.
