"A Little History of C 3/3" says that C was used in the special effects for Star Wars. I do not know what relevance this has, honestly, but independent of that is the strange choice of photo: an image from the Empire Strikes Back which shows stop-motion models with optically-composited, rotoscoped lasers. Excepting that this may be from the digitally recomposited Special Editions, no C code was used in the making of this shot.
