Pencil is a free, open-source sketch mapping and GUI prototyping tool from Vietnam. Its hand-painted style can match the effect of drawing on paper veritably, and can independently run on Windows, Linux and Mac OS platforms or even installed as plugin of Firefox.

In addition to being used to map all kinds of framework and flow charts, Pencil also has built in multiple sketchpads and templates for a variety of platforms. Even, you can use it to create multi-page documents with background and across-page links support.
