Flux is a new XHTML/CSS web designer for the Mac. Use JavaScript to do cool stuff, and add some AJAX to add a tangy Web 2.0 flavour to your designs. Drag and drop elements onto your page, move them, and watch your CSS files get updated without touching a key.
Flux is supplied with some great templates to get you going, but don't feel you have to use them, we won't be offended, go ahead, see if we care...
