Watch as Google reacts to your command. No idea how long these have been on google, but thought id share as ive never heard of them before.

Cant link it, but on google maps type "The shire" in A and type in "Mordor" in destination and choose walking directions

Type Goggle gravity and hit I'm feeling lucky. :)

Google gravity.. I really should learn to proof read.

One of my favs is typing in "Google l33t speak" then click "I'm feeling lucky", and http://www.google.com/pacman/ when I feel like playing pacman :)

I tried to check it out didn't work for me i need google chrome or something eh?.

the ones I posted works on explorer and chrome...the modor one works regardless of browser. I think the barrel roll may need firefox or chrome though.
I have no idea what the gravity one does...

There was one that was like "let it snow" or something. Not sure if it still works.
