Hatch like shadows for toon shader

[bzemer]

Hi,
Me and my friends in college, thought that it would be a great option to shade by hatching, much like in real sketching.
here's a reference: http://www.sketch-a-day.com/page/11/

Thanks!

yes this would be really awesome!!
having that one could directly build the 3d model of an idea and make the "true story of the development" around it after that - only by the rendering software:
- sketch (white black lined toon shader with hatch like shadows)
- CAD (coloured toon shader with standard shadows)
- Preview Rendering (low Quality rendering using default settings)
- final Product (high Quality customized rendering)
