Using CSS3 To fill a mixed cereal bowl [no IE]

We made this interface for a hackathon and the surprising thing was that it was REALLY easy.

As far as the javascript code is concerned, all we do is add and remove classes and if there weren't vendor-prefixs the CSS would fit in 20 or so lines.

If you want to animate something but it's not critical, use CSS3, it's fun and easy.
