Part of the beauty of this film is where Jarmusch leaves each story. He's rarely been one for buttoned-up conclusions. And here, he essentially offers not even a day, but a few hours in the lives of people bound by blood, and — what else? We get a window into their lives, and a glimpse of how they see each other. Then, their story moves on without us. Where will they go? What will they experience? It's a mystery the movie won't dwell on, but we can.

Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.
