Isn't "3rd dimensional plane" an oxymoron?
Hmmm. I don’t think so but I do think it is incorrectly used here. To me, the 3rd dimensional plane would just be the z axis. If you were talking about the entire 3D shape which they are here, I would just say 3rd dimension.
Neat. How does this help me violate causality or skip over to a different planet? "Scientists discover we are trapped in an even deeper infinite fractal of hell from which there is no escape."
Can I buy this chandelier?
In the Beyond section of Bed Bath and Beyond
Seems to me like it's demonstrating the projection of a complex three dimensional shape which produces a simple pattern on a two dimensional plane.
It's worse. It's the projection of a 3d shape onto a 2d shape, which is then captured on a different 2d shape to be displayed to us.
It also has a brief 4d dimension, sliced at the second the picture was taken.
Rolling shutter, my beloathed…

But what's the time equivalent flashlight?!
Manifolds such as these are actually defined by the maps used from a linear space. Two manifolds (i.e. two sets of maps) are considered the same (isomorphic) if the maps of one set can be "morphed" into the other and vice versa.
The flashlight demonstrates how the manifold's map projects into the linear space. See stereographic projection.
That's kind of part of a larger point actually: There is no 3d vector space in reality. It's a made up construct used to make sense of the world around us.
Pretty much my reaction to NMDS plots, too.
