Good times, right? You bet. But the most interesting part is when you start using the Google Body Browser layering tool. Located below the zoom controls, the layering tool lets you peel back layers of the body (of the body, buddy, not the clothing -- get your mind out of the gutter) to see detailed views of the human anatomy.

Bumping down one level sheds the skin and gives you a glimpse of the muscular structure (). The next level goes skeletal. Keep going and you'll get organs, arteries, and veins -- then eventually nothing but nerves.

Want to learn more about what you're seeing? Just click the "Labels" option, and Google Body Browser will serve as your virtual biology book. With the option activated, tiny labels will appear on every item in your current view, letting you know exactly what you're looking at ().

Of course, it wouldn't be a Google product without search. Type any muscle, bone, or organ into the search box at the top of the page, and Body Browser will instantly zoom into the appropriate part to show you where it is ().

One other neat feature worth mentioning: Body Browser adjusts its URL as you move along, so if you ever want to save a particular view or share it with someone else, all you have to do is copy the current Web address and you're good to go.
