Google seems to be in the Easter spirit, they have made this little Easter game. In the game, you control a bunny that is suppose to catch easter eggs with the letters G,O,O,G,L,E and in that sequence and in the color order. As you win each round, the eggs go faster, change color and you get this happy looking bunny to smile.
Check it out for yourself at Google Easter Bunny and for more information on the applet visit the Bunny Credits page.

Update: The thread did not say this was a new game, as the folks have commented below on this entry, it has been out there since April 2000, at least. See the Google Friends April 2000 Newsletter.
