So it turns out I haven't vanished (and actually have a lot of new content to share) but I've been swamped working on several projects of late. One of them I'd like to share, for those of you who really like dinosaurs but actually have different job aspirations:
I'll be teaching a course for Visualarium, one of the leading educational resources for visual effects artists (and artists in training) that use Pixologic ZBrush. The class is Advanced Creature Anatomy, and rather than being on dinosaurs (although you'll see some of them!) it centers on learning enough comparative anatomy from living and extinct animals to develop your own mental toolkit of concepts you can apply when to design more plausible speculative anatomy for fictional creature design.
I'll do my best to keep it fun, so if ZBrush and 3D art is your thing, I invite you to check it out; we'll be conducting a free webinar this Thursday so people can get a taste of what the course will be like.
