Day and Night is a cellular automaton rule in the same family as Game of Life. It is defined by rule notation B3678/S34678, meaning that a dead cell becomes live (is born) if it has 3, 6, 7, or 8 live neighbors, and a live cell remains alive (survives) if it has 3, 4, 6, 7, or 8 live neighbors, out of the eight neighbors in the Moore neighborhood. It was invented and named by Nathan Thompson in 1997, and investigated extensively by David I. Bell. The rule is given the name "Day & Night" because its on and off states are symmetric: if all the cells in the Universe are inverted, the future states are the inversions of the future states of the original pattern. A pattern in which the entire universe consists of off cells except for finitely many on cells can equivalently be represented by a pattern in which the whole universe is covered in on cells except for finitely many off cells in congruent locations.
Although the detailed evolution of this cellular automaton is very different from Conway's Game of Life, it exhibits complex behavior similar to that rule: there are many known small oscillators and spaceships, and guns formed by combining oscillators in such a way that they periodically emit spaceships of various types.
Day and Night is a 2004 Chinese film, and the second film by Sixth Generation writer-director Wang Chao. It is also known, less accurately, as Night and Day. The film constitutes the second entry in Wang Chao's loose trilogy on modern China. It was preceded by Wang's 2001 debut, The Orphan of Anyang, and would be followed by Luxury Car in 2006. The film is a Chinese-French co-production between Fang Li's Laurel Films and Sylvain Busztejn's Rosem Pictures in association with the China Film Fourth Group and Arte France Cinema; Laurel and Rosem would later reunite to produce Luxury Car.

It is considered by some to be one of the worst films of all time.
