Guy Ngan’s 'Data General [mural]' extended along the corridors of a commercial building in central Wellington. Optically challenging as an artwork, rectangles of 3M reflective adhesive dance up and down the walls, punctuated by stainless steel strips. Horizontal and vertical lines collide, enhanced by fluorescent lighting strips on a reflective ceiling. Ngan’s idea was to bring in some light to an otherwise dark entrance way.

Ngan would later experiment with reflective surfaces in his mural for the National Bank in Hamilton.
