Anyway, I've rambled enough, so I'll just say that is a movie about the inversion layer on Mauna Kea, showing how the clouds come down after sunset. The camera is facing more or less west, and I took an image about every 15 seconds. You can watch as twilight deepens into dusk and the clouds from up above flow down the mountain to lower elevations.
And it's somewhat ironic, I guess, that just as I get the ability to make stop motion movies again, I also get a new phone with a bona-fide video camera built in. Of course, I can hardly wait to see how I'll be able to use that!
