Unfortunately, that's not a picture of the amplituhedron. I'm pretty sure that's like glass or something. The amplituhedron is a high-dimensional object that can't be meaningfully viewed by humans, which doesn't make it stand out significantly from most of the stuff that theoretical particle physics pumps out. Also, while it simplifies certain computations immensely, it's still unclear (after three years) whether it actually applies at all outside of a very specific toy case that is almost certainly not what our universe consists of; again, not significantly different from most of the stuff that theoretical particle physics pumps out. Also the article completely botches the description in many, many ways. Again, not a significant difference. It is kind of elegant as a construction, though.
