Are you referring to the way in which the concave form takes the diffuse and faint and focuses into something with far more impact? Sort of like standing under a dome and clapping your hands can be deafening, but out in the open, it quickly fades? Or how it can take light and focus it into a point hot enough to set fire? Or the way skilled propagandists can coalesce random and individual, yet widespread discontent into a powerful movement?
