Today I came across simple and nice to have utility software “Pencil”. I found it very useful for designing professional looking mock-up in a matter of an hour.
Standalone installer is available for both Windows and Linux, but the interesting thing is that it can also be used as the Firefox addon.
My favorite Stencil is “Sketchy Gui”, It simply looks great on paper.
Installer comes with bunch of stencils and many more stencils are available for download at http://pencil.evolus.vn/en-US/Downloads/Stencils.aspx
If you wish to contribute to this great software, here is the project link http://code.google.com/p/evoluspencil/downloads/list
Many Thanks to Developers of this Software.
