On Kawara's "Date Paintings" (1966). "Each of On Kawara's "date paintings" was completed on the date shown, the painting's sole image. Collectively they're called Todays, and the artist has made over 3,000 since the 1960s. Should he fail to finish a painting by the stroke of midnight, he destroys it. You imagine his failures to make the deadline -an unexpected visitor, the artist was struck down with sudden toothache... time ran out. "-- Adrian Searle (in a review for The Guardian, 2003)
