Self-reference is just the sort of mathematical amusement that entertains Google engineers . Searching for “recursion” suggests that perhaps you meant to search for “recursion.” If you click Google’s suggestion, a new page will load, but “Did you mean: recursion” will remain at the at the top of the results list.
7. Google Earth Flight Simulator:
Google has this very interesting Easter egg hidden in Google Earth. Using the flight simulator, you can fly around the globe in Google Earth by simply pressing Ctrl + Alt + A. This activates the flight simulator and allows you to fly an F-16 fighter jet anywhere in the world. This, however, was originally inserted as an Easter egg but now has become one of the official features of Google Earth.
8. Play ‘Snake’ In YouTube Videos:
If you open a YouTube video, click in the frame right after the video starts loading, then press the Up+Left arrows simultaneously you can enjoy a game of “Snake” over the YouTube video.
9. Google Anagram:
Search the word ‘anagram’ in Google and it will display ‘Did you mean: nag a ram‘ on top of the search results page. If you are wondering what could that strange term (nag a ram) mean then it is an anagram of the word ‘anagram’!
10. ‘What Is The Loneliest Number’ and More Google Calculator Fun Answers
Search for “What is the loneliest number” and Google’s calculator will tell you that it is “1”. The calculator returns the same answer when you search “the number of horns on a unicorn.” as well.
Similarly, search for “baker’s dozen” and the calculator returns “13.” Searching “once in a blue moon” yields a comically small number.
NOTE: To try some of these hidden Google Easter Eggs out, you’ll have to switch off Google’s Instant Search in your settings, so you can access the I’m feeling lucky button. Also, for some of these hidden Google Easter Eggs to work, you’ll probably have to use a browser that supports HTML 5 technology. At least Firefox 3 or IE7, Chrome and Firefox 4 are automatically up-to-date.
