This is worth checking out, its another neat little tool building further on Blueprint. It demonstrates the promise of the tool we all need, a WYSIWYG HTML/CSS editor that works dynamically inside a browser. This means all the development and previewing/testing is done in the browser, no intermediate application. Bill Hill’s wish list provides a good description of such a tool.
Another handy little tool is TypeChart which lets you see the typeface and retrieve the CSS.
