No. 14 of the TYPEWRITTEN series: You Might Not Know an Algorithm Until You've Typed it by Paul Prudence, UK.
 
Paul Prudence: "All drawings in this collection were made by repurposing an ordinary typewriter to behave like an electronic plotter. By placing a pen tip in the eye above the typewriter guide I was able to draw lines of different lengths by guiding the paper in any direction using the roller, the space-bar, the tab, the shift and the backspace keys. The algorithms explored in these drawings were related to stochastic systems, randomness and non-determinism; recursive systems, feedback , emergence, space-filling curves and cellular automatons."
