Want to see some easter egg on Google? Well then go ahead and open Google and type “Do a barrel roll” without quotes and voila!
You will see the search results page make a complete 360 degree turn before coming to a halt at its standard position. Alternately, you can also type “z or r twice” to see the same effect which is a code for Star Fox.
The barrel roll animation was created by a Google Engineer to showcase the merits of CSS3 that is supported by most of the browsers today. The query will spin the search page a full 360 degree. The animation won’t be seen in older browsers that don’t support HTML5 and CSS3. The animation therefore works on Chrome and Firefox but not on Internet Explorer.
