A system for producing drawings where the form is determined by chance. - 1p landed off paper once, £1 landed off paper once, £2 landed of paper twice, £2 was repositioned twice. Using a 1 metre length of string drop consecutively a 1p, 2p, 5p, 10p, 20p, 50p, £1 and £2 coin onto a sheet of A1 paper as central as possible. If the coin lands off the paper re-drop it. Then draw round the coins in the order dropped corresponding with their value with a 0.1 pen leaving a space of 0.1 between each line. Predicting whether a coins lines will exceed the edge of the paper can result in a re-drop. The drawing is finished once all the coins have been drawn round corresponding to their value.
