Sol LeWitt (1928-2007, USA) produced more than 1,200 wall drawings, executed by himself and other artists. This time-lapse video shows the gallery wall drawing in progress, with two artists following LeWitt’s original rules. The execution of this wall drawing formed part of the exhibition ‘Sol LeWitt: Artists’ Books’.
