I added iPad app bundle (see bottom row in the following image) on the advice of another yoga teacher that practices at the same studio (thank, Kurt). It is Visible Body. This particular bundle contains Atlas, Skeleton, and Muscle apps. There are 3D views with pan, tilt, zoom. It costs around $40. I’ve including some screen shots. It’s a great way to learn about anatomy and to supplement the Trail Guide.
