Here’s a very cool use of the Google Earth Plug-in — a well-animated clock. When you load up the site, it shows you the current time of day by using various locations in Google Earth that resemble the appropriate digits. However, rather than displaying static images of the numbers they actually load five instances of the Google Earth plug-in that are refreshed every few seconds to show new locations.
To try it for yourself, simply visit googleearthclock.cwandt.com.
They also have a link at the bottom of the page to allow you to submit new locations to show the numbers and colons, which will help it become even better over time.
One final touch I noticed is that if you keep your mouse off of it for a few seconds, all of the other text on the page goes away leaving only the clock on a black screen. It’s a nice effect.
