If you get bored of surfing the traditional Web, there are a few dozen hidden Chrome pages that you can check out on your browser. All you have to do is type the Chrome URL (usually begins with chrome://) into the Omnibox. Some of these addresses are pages you find via Settings, but some are only available via a direct link.
Most of these pages are hidden for a reason, because you'll never need to use them. They're just under-the-hood info for coders and developers. You can find an official click-able list by typing 'chrome://chrome-urls' into the Omnibox. If you're curious as to what they mean, Ghacks.net has put together a list of what each is used for.
