David Earle's eerie Dining Room is a short with an odd concept:
"This short film flips back on itself. At exactly the midway point, the film begins to run backwards, and the sound repeats itself backwards with it. The character (Lea Porsager), speaks the three words backwards as the film goes forwards, so that they can be deciphered at the end of the film when they are played backwards."

Sort of like if the inhabitants of The Black Lodge were allowed to run the whole movie.
