Ah. My apologies, and thanks for your patience with me.
This is the whole thing — you can see most of those stacked replicators (not particle emitters). The rocket engine is Replicator 18, The steam engine is Replicator 03, etc. All the emitters are box, random, and in more or less the same place in 3D space, creating a big cloud of random pages to fly through. Like the Millennium Falcon in the asteroid field. ☺
