After taking a diploma in Anatomy and Physiology, I needed a quick reference tool to refresh my memory when dealing with different areas of the body. The Human Body Cube fits the bill perfectly, and saves thumbing through pages and pages of books.
Although it doesn't have room to list every single muscle etc, there is an abundance of information on such a small area. Although fun to use, this is not really a toy in the true sense, but a handy learning aid which is compact enough to carry around. I would thoroughly recommend this to anyone with an interest in Anatomy, and especially those who are studying the subject. Just wish I'd had one of these when I was doing my coursework.
