Google's Barrel Roll Easter Egg

If you use Google to search for [do a barrel roll] in Chrome, Safari or Firefox, you'll notice that the search results page actually does that. It's a brilliant Easter Egg that will surprise a lot of Google users.

According to Wikipedia, "a barrel roll is an aerial maneuver in which an airplane makes a complete rotation on its longitudinal axis while following a helical path, approximately maintaining its original direction."

There are at least four other Google search Easter Eggs: ASCII art, anagram, recursion and tilt.
