Sol LeWitt explored line and shape and size - and how art is made. One wonders whether he envisioned visitors fitting into the artistic landscape of stripes, left.
Wall Drawing 797, above, is a good example of Sol Lewitt's work: he left instructions on how the art would be done, rather than an actual physical piece. In this case, four drafters work, with the first drawing a blue line, the second a red line that follows the blue line without touching it, the third a yellow line that follows the red line without touching it, the fourth a blue line, until the bottom of the wall is reached. The original line is random and the patterns emerge from the process.
