Chinese illustrator Li Yong Hong works in scratchboard, a medium that is almost the inverse of pen and ink.

Instead of drawing in ink directly on a white surface, scratchboard is done on a white board that is coated with clay and then coated with a layer of black ink. The black surface is scratched away with needle-like styli, creating white lines by revealing the clay beneath.

The only presence I’ve found on the web for Li Yong Hong’s work is his portfolio on IllustrationX.
