Boarded flight to Ōsaka. 👋 北海道! The young salary man in the seat next to me probably weighs half as much as I do, but splays himself like a crab twice his size. I’m pretty good at folding myself up, but buttoning the top of my blouse without invading his space was complicated origami.

Basic models of flocking behavior are controlled by three simple rules: 1) separation: avoid crowding neighbours (short range repulsion); 2) alignment: steer towards average heading of neighbors; 3) cohesion: steer towards average position of neighbors (long range attraction). With these three simple rules, the flock moves in an extremely realistic way.
