The WebKit developers are working hard on new CSS3 features. Last night Dave Hyatt mailed the webkit-dev mailinglist and blogged about the fact that box-shadow is now completely supported. I've quickly created a preview page for it. Then fellow CSS3 enthusiast Nicholas Shanks spoke to me on IM today and told me that the WebKit developers are working on supporting multiple column layouts as well. If you upgrade to the latest nightly, you can see their progress!
