  We investigate several topological and combinatorial properties of line
arrangements. We associate to a line arrangement a link obtained by
intersecting the arrangement with some sphere. Several topics are discussed:
(a) some link configurations can be realized by complex line arrangements but
not by real line arrangements; (b) if we intersect the arrangements with a
vertical band instead of a sphere, what link configurations can be obtained?
(c) relations between link configurations obtained by bands and spheres.
