When I was at Case Western, one of their big selling points is that they were developing one of the first VR anatomy programs. They're hoping to implement it fully for students within the next 5 years.
I tried it-- it was very cool, but was clearly very preliminary. They warned us that the bodies were currently an artists rendition and, while they looked realistic, were not anatomically accurate enough to teach med students yet.
So, that makes me a little skeptical of this $30 program. But hey, it might be worth a shot to help you visualize some of those odd things, as long as you corroborate info w other sources.
I do have the Visible Body 3D atlas app on my iOS devices and love it for that reason.
