Pencil Drawing
Josh over at tinyscreenfuls is digging some of the fancy “pencil sketch” effects that the Mac can do with its internal camera. Back in 1998, I experimented with writing some filters that did much the same, with some examples that I generated shown on the right.  Macintosh? I don’t need no steekin’ Macintosh. 🙂
And now, for your next project, render an entire feature length film. Â Beneath your desk, you’ll find a pencil, a yellow pad, and a C compiler…

Ostromoukhov, etal. have done some pretty nice pencil work.
