Google recently snuck in another fun
Easter Christmas egg; a festive snow effect, with a steamy twist!
Searching for let it snow adds snow-fall to the results page, no-doubt to distract you while your browser window subtly mists up.
Delightfully, you can then draw in the steam.. or in my case, scrawl swear words.
Oh, and defrost button is sensibly provided, should you decide that you really ought to do some work today.
