Mysterious appearances in Dotland

Once again the SNEAC building is the site of uncanny occurrences. Bundles of curious metal cages have been appearing in unusual places, then disappearing and reappearing in other places. Some sort of structure is being built across the ceiling, going around the edges of the room, disappearing into holes in the ceiling even though no workers are ever seen. Is this some sort of Close Encounters thing? Are aliens building a mysterious device to trap the inhabitants of the SNEAC building? (Well, probably aliens are building it. Aliens do all of the construction in Arizona.) Silver thinks the new structure looks like a hamster run. Sage is hoping it's a track for an electric train. She thinks a nice train running around below the ceiling, blowing its whistle at crossing, would add a nice homey atmosphere to the place. Bringing the Dots back down to Earth, Black-and-Yellow Dot of Bombs and Engineering, says the new structure is cable runs for wiring. Of course, one of the other Dots heard a rumor that the SNEAC building is going wireless. Let's see. The SNEAC building is currently wired but doesn't have any cable runs. Now it's going to be wireless so they are installing cable runs for the non-wires. Makes perfect sense.
