Simple pendulum effect using CSS3 animations.

This is my absolute first CSS3 animation! I'm pretty excited about the possibilities and will definitely be reading some of the recommended books on the subject.

Here's a simple pendulum effect I wrote using CSS3 animations. I'm using the -webkit- prefix, so this won't work on Firefox or any other non webkit-based browser.

I'm really impressed at how well and intuitive CSS3 animations feel. The use of percentages to indicated keyframes is just wonderful.
