The world is a giant multi-dimensional ball hurling through possibility space.
We forget that it's got momentum, that the whole thing's a vector pointed somewhere, moving through the jungle of whatever else is out there. Maybe other worlds.
Say the universe is made of bubbles. It takes a while to see it, then you get knocked back and can't unsee it.
Bubbles that orbit bubbles that orbit bubbles. From there, you get all sorts of hairier superstructures involving filaments, linkages, walls, grates, zig-zag backgrounds, super-polymerizations into tissues and organisms.
