At the recent JSConf.be conference here in Belgium, Ibe Vanmeenen gave a very nice talk introducing Houdini.
CSS as a language is at the brink of a great revolution. Once such a closed and magical language, it will open up to you and your creativity in all it's glory. CSS will become an easy to expand and polypill language, all while keeping the performance at an up-high. All hail Houdini!
The talk itself has a very nice build-up, and Ibe’s a great speaker. Highly recommended!
