Hidden treats from the web behemoth. From the Telegraph (UK).
GOOGLE READER NINJA
Probably the finest - and certainly the most childish - Google Easter egg. Using the arrow keys, type "up, up, down, down, left, right, left, right, B, A" while using the firm's RSS feed reader, and a little ninja appears on the left of the screen, which turns partially blue. It's a play on the cheat code that worked on early Nintendo video games produced by Konami, the Japanese entertainment company.
GMAIL SPAM RECIPES 
The suggested links that appear in the bar above GMail inboxes are - depending on your view - entertaining, irrelevant or annoying. But you can't help but smile at the recipe ideas that appear in the same bar of the spam folder. The menu includes Spam Confetti Pasta, French Fry Spam Casserole and Spam Breakfast Burritos, and best of all they link to real recipes.
STEVE IRWIN
Most of the 3D buildings that appear in Google Earth have been sketched by independent designers, some of whom managed to sneak in easter eggs of their own. Spin round to the waterfront side of the Sydney Opera House in Australia and you'll find a model of the late wildlife expert and adventurer Steve Irwin wrestling a crocodile.
GOOGLE EARTH FLIGHT SIMULATOR 
As if soaring above the planet wasn't enough, Google Earth allows users to fly an F-16 fighter jet anywhere in the world. Simply press Ctrl + Alt + A to activate the rudimentary flight simulator; you can learn the controls here. The simulator was originally inserted as an easter egg but has since become one of the official features of the programme.
BLUES BROTHERS BRIDGE JUMP 
Another 3D buildings easter egg hidden inside Google Earth, this time recreating the famous bridge jump scene from The Blues Brothers, the 1980 movie starring John Belushi and Dan Aykroyd. That was filmed in Chicago, but the stunt is reproduced for Google Earth on the Tacony Palmyra bridge linking New Jersey and Philadelphia.
