You should know that Google has a sort of Google Maps application, only it’s not for real maps, but for the human body. It’s a pretty awesome and nifty tool, especially if you’re into anatomy at a basic or intermediate level, or if you have problems visualizing the human body, or even if you’re just curious.
Here it is.
Some people report browser problems when using it, getting this message: Welcome to Google Body. You need a Web browser that supports WebGL. I tried it in Firefox 4 and got the same message, I’m not sure what the problem is, but it works just fine with other browsers.
