What about mid-day naps?

"6052 days + nights (8.29 years) (vellum and insect pins on vellum-covered foam board), by Ann Wessman, in her show "Being Vertical + Horizontal,''  at the Kingston Gallery, Boston, through Oct. 2.

The gallery notes say that the exhibition "honors each day of life with a simple, repeating pattern of vertical and horizontal orientations representing the states of awake and asleep and day and night. The artist asks us to view her labor-intensive installation as a calendar.''

The horizontal pieces of paper, of course, represent night and the vertical ones day.
