I love stuff like this. Andrew Hedges with a bunch of WebKit (the rendering engine that powers Safari, Google Chrome, and Palm Pre) CSS tricks including CSS animation.
Other browsers will hopefully implement these techniques as well. Apple have proposed all of the techniques I’ve used in my examples to the appropriate standards bodies. My guess is Mozilla and Opera will get on board relatively quickly. When The Beast decides to grow a round tuit is anyone’s guess. IE12, perhaps?
We should be so lucky. WebKit spoils us. IE soils us.
