@uhoh I'd heard of the gimmick reservations, and I think I saw an image of it once, but it wasn't anything like the sketches in that article.
It was far more fanciful. I find it very intriguing that the design in article is so conservative. It makes me feel like it was indeed a little more that just PR.
