As the animation loops it uses the same set of images over again. But as they all have a Cache-Control header with a value of "public, max-age=0, must-revalidate" the browser makes another request for every one of the images, every loop of the animation. It results in transfer of something of the order of 0.6MB/sec, with no end.

How do we know the frames aren't generated and streamed on-the-fly from mocap on a real live eagle?

Can I reuse the eagle animation on my own website, using trumpcard.gov to serve the images? A PoC would help.

And it's clearly AI-generated. As if one couldn't find a video of a bald eagle.
