Working recreations of the software that planned and flew the Apollo missions, with the documents they came from.

The first entry rebuilds the view program. NASA's Manned Spacecraft Center used it to draw what Apollo crews would see through their windows and telescopes, and filmed its output frame by frame. The film here is the recreation's output, computed in your browser one frame at a time.
