Holy subprime seasons. While it was always possible for an entire neighborhood to synchronize its lights, it wasn't possible to actually see it until last year. It's really a sight that cost a fortune until the rise of the quad, higher sensitivity cameras, & then the brushless gimbal. Of course, flying a quad that high above a neighborhood is a very nerve wracking experience for someone who's done it long enough to experience a few crashes. It almost makes our taxes to support the house flipping industry seem worth it. Now if only batteries lasted long enough to make timelapses.
