Almost as fun as the katamari hack:

Now THAT is awesome. Needs an HN thread of its own.

HN is where I heard about it. Here's the thread: http://news.ycombinator.com/item?id=2318076

Works especially well on word-heavy pages like PG articles (http://www.paulgraham.com/road.html) or Timecube.com

I believe this is a takeoff from the demo of box2dweb:

Pretty cool. Type something into the search box, press enter and see what happens. :)

This experiment was done in 2009 using Box2DJS[1] for the site Chrome Experiments[2]. Since then I've been improving it by cleaning up the code, adding DevideOrientation support and, some weeks ago, updated it to the new google.com design.

Fun fact: The API being used has been deprecated for a while and, as far as I know, there is no alternative.

Amazing that it works on non-Chrome as well, then! (opera, in my case)

(also, hi! small world)

Mr. Skrebbel! :)

Yes. Chrome Experiments is not about Chrome-specific experiments but about pushing Javascript and the new cross-browser APIs.

I always try to use APIs supported by more than one browser. It just happened that it performed much faster on Chrome than any other browser for a year or so (until the other browsers catched up).

Good to see that, 2 years after relase, people on Firefox/Opera/IE can finally see the thing properly ;)

Yeah, good thing Box2D doesn't change a whole lot in itself, and is pretty complete. Recent commits have mainly been small refactoring changes.

Thanks for clarifying! It's a really great idea!

Awh, they removed the Google+ part of the toolbar. I want to check my notifications upside-down.

It's just the not-logged-in view.

The alternative would be a security hole in Google.

Lo he adoptado como mi pagina de inicio al http://mrdoob.com/projects/chromeexperiments/google_gravity/ Muy buena iniciativa y muy original. (I've adpted as the Home page. Original and creative one, puts a smile on the face. Keep it going. Congrt!

On my phone so I can't accurately find it, but there was an ad for a Nintendo game (Wario: Shake It) that added gravity to Youtube. It was done fantastically. Someone should link that.

I guess it is this: http://www.youtube.com/wariolandshakeit2008

It even works if you move the browser window around

Works great on touch devices as well.
