Testing the Animation Nodes add-on for Blender. Fairly quick to animate lots of objects (in this case, the buildings’ rotation and scale is based on distance from a key object, so their animations end up staggered).
Had issues with rendering. AN kept throwing an exception and stopping working halfway through the render. Got to either have AN burn keyframes (to all those objects… [gulp]) or just write a script to do it.
Buildings and road data from OSM.
