One single line weaving backwards and forwards through 2280 spirals to form a male torso. This was one of my earliest spiral drawings and where I usually plot two lines of different colours on top of each other, this is just a single line, which allows the spirals to stand out more clearly. You can see further detail on the shot below.
It was drawing using a single Bic Biro, took around 12 hours to complete, and if unravelled would stretch for 180 metres.
Materials: Bic Biro on paper
Equipment used: Pen plotter; Raspberry Pi single board computer; Inkscape to control plotter; Affinity Designer to draw spirals; LibreOffice Calc to organise data
