Another timelapse, this time focusing on the "tennis court". Unfortunately due to inherent laziness this is in reverse order, but in a video player it's easy enough to go frame by frame by clicking the timeline bar.

Seeing the images in motion makes it easier to spot the development progress. I'm gonna call it being in reverse a feature since it's easier (for me at least) to see things disappear rather than appear. For example, the track that develops over time from the pond on the right side of this sequence up the hill to the point inbetween the tennis court and the sun dial, maybe used for hauling things up the hill.
