There’s a UPS parking lot packed with truck trailers behind our Hell’s Kitchen office. On any given day–but during the holiday season in particular–the place is buzzing with activity, as its delivery fleet hitches up to and drops off the trailers. Due to space constraints, this plays out like an IRL game of Tetris, which we captured from a camera mounted on our roof in this 24-hour timelapse. Watch the entire puzzle-like dance play out in about three minutes above. Good luck making it through to the end. (Video: Aymann Ismail/ANIMALNewYork)
