This is what we want.

Just amazing what techy stuff can do ...

Abstract: We propose a method to realistically insert synthetic objects into existing photographs without requiring access to the scene or any additional scene measurements. With a single image and a small amount of annotation, our method creates a physical model of the scene that is suitable for realistically rendering synthetic objects with diffuse, specular, and even glowing materials while accounting for lighting interactions between the objects and the scene. We demonstrate in a user study that synthetic images produced by our method are confusable with real scenes, even for people who believe they are good at telling the difference. Further, our study shows that our method is competitive with other insertion methods while requiring less scene information. We also collected new illumination and reflectance datasets; renderings produced by our system compare well to ground truth. Our system has applications in the movie and gaming industry, as well as home decorating and user content creation, among others.

Along with the Selectors3 REC, CSSWG publishes the First Public Working Draft of Selectors Level 4. Yes, CSS4!

Selectors Level 4 (W3C Working Draft 29 September 2011)
http://www.w3.org/TR/2011/WD-selectors4-20110929/

What's coming? Well, you can finally select a parent of an element. You can change the subject of a selector by putting a dollar sign ($) before a compound selector.

ul > $li > a { background: #eee }

The declaration applies to <li>, not <a>.

Selectors4 adds many more: :nth-match(an+b of selector) for more conditioned structural matching, :matches() for less-verbose selector declaration, etc.

Some new selectors (like :matches() or :any-link) originated in vendor extensions (:-moz-any() or :-moz-any-link). I hope this time it won't take more than 10 years to be finished.

Did a CSS Performance talk at the CSS Summit (online conf) today. Slides are here: http://dl.dropbox.com/u/39519/talks/cssperf/index.html I talked about Reflows, Selector and Rule performance, Expensive style properties, Polyfills and Debugging & Tools.

The slide deck probably doesn't make a lot of sense solo. I'm going to record a screencast soon to capture this talk. In the meantime my http://paulirish.com/2011/dom-html5-css3-performance/ screencast dives into reflows well.
