In 2008 I began reexamining this landscape by running the Rickety drawings through a paper shredder. Each resulting shred carried a residual history — present yet inaccessible — that connected it to the drawing it originated from. As I searched the mounds of shreds and studied these traces, found bits of line and form were discovered, combined, considered, surgically excised and recombined as unexpected images took shape. The new drawings are cross-indexed manifestations of reprocessed thought. They are also cairns — physical markers to which imagery, ideas and memories are tethered to within the stream of forgetting. Their fragility and ambiguous imagery pair with the machinery used in their creation (computer, scanner and shredder) to clumsily ask the question of what it means to think.
