«Brake» (2014) is a clash of horizontal and vertical stripes, with swaths of ochre drifting across the surface and a band of
intense cadmium yellow along the upper edge, while in «Raft,» (also 2014), the vertical stripes run from top to bottom, with two horizontal sets constrained within shield - like shapes on the left and right, calling to mind Walker's fascination with Aboriginal and African art.
