Google’s Chrome browser offers a three-dimensional model that lets users zoom in and out of the human form, remove layers, and explore the body. You need to have the Canary beta version of Chrome. Other options are to use Firefox or Safari with an WebGL Implementation like Kronos. You can view the nervous and digestive systems, zoom in on the skeleton and bones, and also play around with how they are interrelated. You can term the body around to take a look from the back or side. you can also stick some names in the search box, like “vagus nerve” and the organ or part of the body is displayed.
I could see this as being useful for teacher training/yoga emersion class or for just learning what lies under the skin. Unfortunately, there is no browser applet for the “subtle body.”
