Last night, Brazil had its largest protest in 20 years.

We posted pictures from the protests (which have various economic causes, including a recent decision to hike bus fare), but from a typical ground shot it can be hard to grasp just how large the turnout was.

However, a 6-second video from a building really captures how epic the event was.
