The spiders or nano cameras are like tiny grains of pollen, once they drift into place they are static. What they lack in mobility they gain through sheer ubiquity. We are seeing the world through these cams, that’s why the shots are mostly static. Suggests and interesting treatment for stabilizing the hallway shot, and having it happen over several perspectives. Coming into the tunnel through several static shots makes way more sense. The pollen has an affinity for human DNA, it tends to anchor at sites where humans have been or are.
