Marking Derek Sullivan’s first commissioned architectural scale wall drawing, “Problems That Arise from Continually Confusing Left & Right” depicts a 10-segment folding ruler and is rendered in coloured pencil. By occupying a space above the reception desk that might normally be used for wayfinding, Sullivan’s drawing raises the problem of mixing up directions from our fluctuating “central” position. Subsequent versions of “Problems…” can be composed using a template and set of instructions provided by the artist as a conceptual in situ work. Each variation of the work, with searching left and right forays, takes “measure” of the chosen wall. Thanks are extended to the following artists for their generous assistance in the creation of the drawing: Jane Derby, Erin Milliken, Sara Perosa, Joan Scaglione, Anna Soper, and Aida Sulcs.
