Brushed metal gets it name from the "brushing" of the surface to give a uniform surface. This is actually a series of very fine parallel scratches, which may be considered a multitude of long but very low mirrors. By orienting the direction of the brushing, compelling light changes can be seen to occur as the viewer walks past.
Brass, stainless steel, and aluminum are most useful for artwork. While brass and stainless steel have a characteristic color, aluminum can be anodized or dyed in a range of interesting colors.
