Random light and shadow

“ A line drawing was transformed mathematically into a shaded image. Then a spiral, rectanle, triangle, and a star were used as a character symbols through each line segment. A random number generator determined the intensity; size of each symbol in a function of it’s distance from a reference point outiside the picture.”
