Google Easter Eggs

Google has recently included some Easter Eggs into its Search!
Don't want to give it away completely but just try this:

On a Computer Or Mobile Device Google:
'Do a barell roll'

Isn't it so cool! Try it out! There is also another, less entertaining easter egg, but try it anyway:
'tilt' or 'askew'

Let us know in the comments if you find any others!
