Drawter - Drawable Markup Language
Yesterday I came across Drawter.
Drawter allows you to draw your HTML/CSS Markup,it is a Javascript application written with the jQuery library. Although it might look like yet another WYSIWYG HTML Editor it is not, it is the best web-based application for the interactive creation of Markup I know.
This picture is taken from the screencast:
Currently Drawter is in Beta 2 stage, but it has already some pretty cool functionality. Plus it is very stable, and works in all browsers .
It is mentioned that there will be an upcoming release called Amateurs which will enable users to “draw” websites without any knowledge of HTML or CSS.
I think this tool is quite useful if you want to quickly create prototypes or Website drafts.
Go check it out: Drawter, there is also a Screencast for a basic overview.
