This timelapse video shows the SpaceX barge (or ASDS: Autonomous Spaceport Drone Ship) "Just Read The Instructions" (JRTI) and later "Of Course I Still Love You" (OCISLY), as well as the support ship GO QUEST and the tug ELSBETH III, from late 2014 to late 2015 at their berth in the port of Jacksonville (JAXPORT). At the end of 2015, the location of the SpaceX berth was moved, which made it impossible to continue spying on the ASDS currently docked there.
Some highlights:

This footage was recorded with a capture interval of 15 seconds¹ (i.e. one image was captured every 15 seconds) from a publicly accessible webcam located on² the cruise ship "Carnival Fascination" [1], using a bash script I wrote for this very purpose [2]. Every day at midnight, that script took the images it had captured throughout the day and converted them into a 24 fps video. During the last few days, I've concatenated the interesting parts of those daily videos, yielding this compilation video with 60 fps³, which works out to 4 seconds of video per real-life hour.
The webcam was brought to my attention by Reddit user /u/darga89 [3].

¹ Mostly, that is: the first two and a half days of footage were recorded at twice the capture interval.
² That's why only every 4-5th day was captured - the cruise ship simply wasn't in port most of the time.
³ I chose to increase the frame rate because it seemed unlikely that anyone would watch a feature-length version of this video. That's also part of why this video is in 720p: YouTube supports 60 fps only on HD videos, plus I assumed that this would keep quality losses due to frequent reencoding during my improvised compilation process to a minimum.
