The Overstrung Piano

This ink drawing on Fabriano paper, completed over a fortnight in Easter 2006, is around one by one and a half metres. It's a crooked, inaccurate rendition of an overstrung upright piano with the front removed. The strings, by far the most excruciatingly time-consuming aspect, are chirstmas marker and gold gel pen. Well, two gold gel pens. The drawing has annotations embedded within it, describing the functioning of certain parts of the overstrung mechanism.
