This only works if you have a smartphone. Go to Google and type in either “tilt” or “askew”. You might be surprised with the results page that is displayed. Looks like somebody in Mountain View had some fun last Friday! Undoubtedly this was an April Fool, it works on iPhone’s and Android but not on Windows Phone 7 or the iPad. So it looks like the page checks which browser you are using and then if it is either an iPhone or Android phone works it magic. My question is did they do it with CSS or HTML 5? If you have any theories on how they achieved this I’d love to hear them.
