Before I even owned a PC!
Windows is a step up in scale, 1200mm x around 800mm, on this piece I experimented with drill sizes specifically. There is a repeated design in this work, each ‘window’ overlapping the larger one and using a smaller drill bit each time. Still using angular, geometric ideas.
I used a light rope slung behind to provide the illumination, there was little choice at that time with regard to compact lighting, a lightrope didn’t get too hot and was long enough to provide light behind the whole area.
Last seen somewhere in America..
