Each Node has its own, unique culture, though all have some elements in common. With the Moderators allowing some transfers of excess workforce between boards, it is clear that all of the domes have some elements in common.
Board: The circular, massive structure that makes up the base of each Dome. The Threads all move along the Board at some point, though many cross the upper levels and even the base of Dome Control in some cases. Off the threads, things are quieter, with no living things for miles at a time. There are shacks, and small communities of outcasts, looters, and traders, but for the most part, the Board under the Threads is just equipment: drone storage facilities, life support generators, drone-manned Worker Production labs, and the like. Few ever bother to look too closely at their Dome's boards, and that's what these are.
Images: These vary wildly from board to board, consisting of everything from sensory projections of sexual imagery (to sate the workforce's urges without resorting to chemical castration) to humorous images and propaganda to increase efficiency and raise morale. May be displayed on everything from the above multi-sensory, advanced holoboards to simple still-images that span entire sections of the Dome walls.
