The geometric design is a representation of the metre-high choppy waves that can suddenly form on the Sepik River. The white V-shaped forms arranged in two columns on either side of the bark as the waves with their foamy crests. The column of black ovoid forms positioned on the design’s central axis depicts ‘the underwater forces’ that generate the waves. The dotted white lines outlining the black lozenges represent the long ribbons of yellowy foam that blow off the tops of the breaking waves and spread across the surface of the water.
