Mass MoCA blogs a compendium of Sol LeWitt wall drawings, highlighting the rich and varied possibilities allowed by LeWitt's instructions.
"Every time a Wall Drawing is put on display, a group of draftsmen paint or draw a new interpretation of the piece… Only one official interpretation of a Wall Drawing can exist at one time; once the previous one has been painted over, the draftsmen are free to start their work. The draftsmen then use LeWitt’s directions to create their interpretation. However, every draftsman and every space is different, meaning that each time a Sol LeWitt is put on display, it is inherently unique."
