Time Lapse of Sol LeWitt’s Wall Drawing #797
Sol LeWitt’s instructions for Wall Drawing #797 (1995), “The first drafter has a black marker and makes an irregular horizontal line near the top of the wall. Then the second drafter tries to copy it (without touching it) using a red marker. The third drafter does the same, using a yellow marker. The fourth drafter does the same using a blue marker. Then the second drafter followed by the third and fourth copies the last line drawn until the bottom of the wall is reached.”
