It seems like if you wait long enough the gears start moving. On Chrome I just saw the closed aperture for several minutes and gave up, on FF I saw the arm and pendulum moving but that's all, 'til I came back several minutes later and the gears were moving. Haven't been able to get that "gear moving" effect again tho. I think file-size/load-time is actually a problem in this case, even as an art piece, as it's taking so long to load I'm not even seeing the art.

A couple other things: the apple clock is using javascript as well, not just css3 (tho they could if they tried). This one... I didn't dig far enough to see if it's used anywhere in the clock but the hands and pendulum are just css. Remember kids, html + css + javascript != "CSS3" :)

Further, HTML5 is nice but it's being used pointlessly here: <article class="layer zero"> <div class="blurred gear one"></div> <div class="blurred gear two medium reverse"></div> <div class="blurred gear three large"></div> </article> This is an "article?" HTML5 to add semantic meaning is good, using it for no reason... I don't see the point. Overall, KUDOS to the designer/developer! Extremely impressive regardless of any of this.
