... on the varying scales of the task at hand ...

In Paris, there is a street;
in that street, there is a house;
in that house, there is a staircase;
on that staircase, there is a room;
in that room, there is a table;
on that table, there is a cloth;
on that cloth, there is a cage;
in that cage, there is a nest;
in that nest, there is an egg;
in that egg, there is a bird.

The bird knocked the egg over;
the egg knocked the nest over;
the nest knocked the cage over;
the cage knocked the cloth over;
the cloth knocked the table over;
the table knocked the room over;
the room knocked the staircase over;
the staircase knocked the house over;
the house knocked the street over;
the street knocked the town of Paris over.
