Thanks!
There was a little chat here a few days ago abt the Sky Crane fragments and I thought that the 25th flight could provide good targets for a "viewfinder" effect. I recalled @mapperwocky had said he'd counted them all and I had also tried to, so I finished some code I had started earlier, to assemble sequences, and that did it. Stabilization had to be done by hand though. The title image took almost as long as did the sequence; it makes the gif look like a book though 🤔
