Device Orientation in HTML5 (tilt your computer if you have a MacBook & Chrome)

The last three versions of Firefox have supported the W3C device orientation spec. Before that, and going all the way back to Firefox 3.5 more than two years ago, Firefox supported a vendor prefixed version.

Pity the developer didn't include -moz extensions, given the use of -webkit extensions you'd think he doesnt care about anything but Webkit.

About 50% of the things on this page aren't HTML5, but chrome-only features.<p>Bleh for standardization, really.

Or an IBM/Lenovo ThinkPad.<p>They all (ingeniously) use the sudden-drop detection that prevents hard drive head crashes to double as an accelerometer.

it would be cool if GMail and other data sensitive web applications used these APIs so that it would log you out of the web service if your computer had a lot of motion (e.g. someone running away with it).

wrote a labyrinth demo back in the day to demo the Firefox-prefixed version of the API. I've updated it here: <a href="http://potch.me/labyrinth/" rel="nofollow">http://potch.me/labyrinth/</a>

doesn't seem to work on my 2011 air

I'm still waiting for someone to build a popular whack based interface based on this data. I'd love a photo album where I would tap the side of my screen to advance to the next/previous photo.

It seems to only react to two axes (beta and gamma -- in other words, if I rotate my MBP on a flat surface, nothing happens) -- is anyone on a device that provides alpha as well? I know the iPhone does, but this demo doesn't seem to work in Mobile Safari.

No JS required w/CSS media query, e.g. @media only screen and (orientation: landscape) {...}
