If you're looking for a better resolution version of the concept image, as far as I know there isn't one. The original is here, and it's not great: https://www-robotics.jpl.nasa.gov/tasks/showBrowseImage.cfm?...

I just wanted to see the folding concept at the given resolution, just bigger, like God and my pinch gesture intended. No cigar.

Opening the image in another tab then zooming then I suddenly wonder why on Earth this is required. I know it's not malice, but there must millions of people with sub 20:20 vision who don't want to enable the screen magnifier when pinch is ALREADY A THING.
