Very cool new development in free online technology for those of us who are in the healing arts, or are simply interested in the beauty and complexity of the human body. Good has made BodyBrowser, a sort of 3-D mapping of the human body. Check out http://bodybrowser.googlelabs.com/ (you may need the latest version of a Firefox or Google Chrome browser for it to work properly). Use the bar on the left side of the screen to move through the different systems of the body, and click anywhere (or even search) to get more info. Quite cool, for a medical nerd like me.
