Vermiculation

Pattern of irregular, worm-like lines

Vermiculation is a surface pattern of dense but irregular lines, so called from the Latin vermiculus meaning "little worm" because the shapes resemble worms, worm-casts, or worm tracks in mud or wet sand. The word may be used in a number of contexts for patterns that have little in common. The adjective vermiculated is more often used than the noun.
