Merry Christmas! Everyone here at WebdesignerDepot would like to wish you a very happy holiday season and because it's Christmas, we thought we'd indulge in a few…Easter eggs…

Google has become well renowned for the easter eggs that it adds to its products and services. Hidden gems that are there to make us laugh, or think; but mostly, keep Google in the news.

Designed to get people talking, get Twitter tweeting and bloggers blogging, Google's easter eggs are named after the Easter tradition of searching for chocolate, or painted eggs. The intention is to keep us on Google's sites for longer, and maybe have a little fun along the way.

Today we're going to look back on some of the best and more memorable examples, check them out and be sure to give them a try yourself.

Atari Breakout

When you search for "atari breakout" in google images the results page transforms into a live version of the game, allowing you to play it right there and then.

Anagram

Search for "anagram" and "Did you mean: nag a ram" will appear at the top of the page. As well as English this also works in French, Swedish, German, Italian, Russian, Hebrew, and Dutch. Likewise, searching for "define anagram" shows "Did you mean: nerd fame again".

"Do a barrel roll"

Typing "do a barrel roll" into the search box will make the page rotate 360 degrees.

Tilt

Searching for "tilt" or "askew" will make the results page appear slightly off-kilter.

K e r n i n g

One for the type obsessives: searching for "kerning" will increase the letter-spacing where as searching for "keming" will reduce it.

010000100110100101101110011000010111001001111001

Searching for "binary" changes the number of search results found to binary numbers.

Let it snow

In December 2011, searching for "let it snow" would cause the search results page to simulate snowfall. After a while, the screen would frost over, enabling the user to defrost the page by either clicking and dragging the mouse (mimicking the effect of rubbing a frosty window in real life) or clicking the "defrost" button.

The death of DOMA

When the Supreme Court struck down the Defense of Marriage Act (DOMA), Google celebrated by adding a rainbow coloured border around the search box whenever someone entered terms such as "lesbian", "gay", "bisexual", "transgender", "queer", "gay marriage", "LGBT", "LGBTQ", "PFLAG", "Stonewall Inn" or "GLAAD".

I <3 Streetview

If you were to find the Googleplex (Google's headquarters in Mountain View, California) on Google Street View, you would see the product's production team standing outside. Similarly, if you look up Google's offices in both Wrocław, Poland, and Dublin, Ireland, you'll find Google employees lining the streets.

"Peg man" gets a new look

When dragged into LegoLand in Carlsbad, the "Peg man" turns into a LEGO figure. When dragged into Sun Valley, Idaho, he becomes a skier. When dragged into the area surrounding the Arthur Ashe Stadium, Flushing Meadows–Corona Park, he becomes a tennis player.

P-P-P-Pick up a penguin

When dragged onto Half Moon Island, Antarctica, the "Peg man" turns into a penguin.

"One does not simply walk into Mordor"

When walking directions is selected and "The Shire" or "Rivendell" is entered as the start point and "Mordor" as the destination, the directions appear with the following warning: "Use caution – One does not simply walk into Mordor."

Do the Harlem Shake!

Entering "do the harlem shake" into the search box will cause the page to do the Harlem Shake.

VHS mode

To mark the 57th anniversary of the VHS, YouTube added a tape mode option to their video player, which when selected would apply a degraded videotape look to the clip. To make the tape mode option available add "&vhs=1" at the end of a video URL.

Stats for nerds

If you right-click on a video a settings menu will appear with options for copying and sharing. Also included is a "stats for nerds" option, which when clicked will display some advanced information about the video player.

Nyan Cat progress bar

At one point, the standard progress bar on the Nyan Cat video was replaced by a Nyan Cat themed design.
