A graphviz dot graph (idk, ask some bell labs people) having three separate clusters: SCREWTAPES, GAME0 and GAME1 filled with various rooms, and directed edges connecting both within and between clusters. It's grayscale and a bit messy. Edge sources are speculatively labelled with compass directions, that were not enforced.
