Lots of videos lately. This one is on some serious meditation art tip. A grid of time-lapse videos, each from one day in the life of the San Francisco sky, shot from the roof of the California Academy of Sciences. The videos all start and end from the same time of day, letting us watch how the daylight changes throughout the year [this would be cool in a place with actual seasons, and maybe throw part of a tree in the frame to see the leaves come and go].
So put on headphones, set this to full-screen and stare into the gridded abyss of blue, grey and black.
