Sol Lewitt Wall Drawing
Sol LeWitt apparently did not enjoy public speaking so when he stopped by the School of the Museum of Fine Arts, Boston, in 1971, as a visiting artist and lecturer, he proposed making a drawing with the students instead of giving a lecture.
On a wall surface, any continuous stretch of wall, using a hard pencil, place fifty points at random. The points should be evenly distributed over the area of the wall. All of the points should be connected by straight lines.
