Grease Pencil is a tool which allows you to draw freehand in some views, allowing you to annotate/scribble over the contents of that view in either 2d or 3d. This facilitates many easier communication and planning abilities. To use, simply enable it from the View menu (choose 'Grease Pencil...' and click 'Use Grease Pencil'). Then, click+drag using the left-mouse button and the shift-key held to draw a stroke. For more information, check the following page on the wiki: http://wiki.blender.org/index.php/User:Aligorith/247_Grease_Pencil
