Google loves to hide “Easter Eggs” inside many of their products. For instance, if you jump into the About screen on your phone and tap numerous times on the Android version, you will find a surprise. It changes with each new major Android build and is something will always check for the minute one is released. So this little trick in Chrome Beta for Android is just another example of the fun things that Google does to their products behind the scenes.
