In the way that digital cameras have nearly eliminated the need for film for the casual photographer, the computer has almost replaced the artist's sketch pad.

However, the computer isn't always the best choice when you are after a certain "look." That's when pens and pencils once again take center stage. And the combination of the two? That mix can provide even more unique looks.

You know, before they had digital cameras for performing colonoscopies, they used to have to send a sketch artist up there. (Just seeing if my copywriter is awake).
