Google Gravity
The force of gravity is non-existent in cyber space. Google gravity
makes you realize how Google would have been if gravity had been
effective on the internet as well. Just type Google gravity in the
search bar and press the I'm feeling lucky button.
This will take you to the Google gravity page
which, at first look, might appear to be the Google homepage itself.
Wait for a few seconds and you will realize why this Chrome experiment
is called Google gravity. Although the website lists it as a Chrome
experiment, it works on Mozilla Firefox as well, although it does not
work on IE8 and previous versions of IE.
