You are bound to have run into Google playing snowman, though it's not to be known how long Google will indulge one in such delights, like its wonderful Doodle Guitar, which happily does have a permanent  home.

Google plays snowman, by responding to 'Let it snow" typed into your Google search box, whereupon it slowly snows to freeze out your page. Help is at hand however with the defreeze button .

Let it snow on your current page.
With this content script, all the page will show falling snow flakes. Thanks also due to Scott Schiller for his snowstorm code.  And that page will also give you everything you ever wanted (or didn't) about nostalgic decks and turntables.
