In the spirit of the Google "barrel roll," the company has another tricky search result today: Search the words "let it snow" and watch what happens.

Of course, your Google search results will contain videos of that old favorite song, but what's that? Snowflakes falling in your browser? Frost on the Google bar? Could this be some mistake?

Watch your browser fill up with snow, and then skate around with your mouse, where your browser acts just like a frozen lake, showing the path your cursor has taken. Want to start over? Simply click the "defrost" button and again you'll see a clear screen, adorned by that easy wind and downy flake filling it up anew.

What a lovely Easter egg Google has given us this cold and snowy (in some places) December morning, just five days shy of the darkest evening of the year! Nice, Google.

UPDATE: Google's also celebrating Hanukkah! Type the word "Hanukkah" on the Google search form and you'll see a special surprise.
