Want to see a sexy, JS and CSS powered clock? Crank up Chrome, Safari or Firefox 3.5+ and point your browser here.
As mentioned, the clocks are using only JS and CSS rotation to accomplish the animation. No Flash or HTML 5 canvas tags. The way it works is kind of clever, actually… the JS takes images in an { overflow: hidden } <div> and rotates them using the proposed CSS transform property.
The author, Jon Combe, has published some other clever goodies including a function that draws world maps on the fly using HTML 5′s canvas. Pay him a visit, click around and enjoy.

Hi Leonardo,

Thanks,
Jon
