Online Courses in Visual Effects & 3D Animation for Film & Games Over the past year, we've been working hard at developing a brand new online training platform for Gnomon. While we have been providing online training for years through both the school and the Gnomon Workshop, we wanted to create a new experience for our students. For over fifteen years, Gnomon has trained thousands of artists on our campus in Hollywood.
