I had a similar impression, while I do see the straight lines that the video is mentioning, I also see his whole thing about growing wings a bit more like letting imagination run with the clouds, which is fairly common.
What I was thinking while watching it was that clouds are essentially water and water is easy to shape by either a physical object, or force.. so perhaps it's a phenomenon and not an object? I am thinking that perhaps electromagnetic forces could create a field that would shape clouds into square shapes... not an expert so I am not sure. But cubic clouds are strange in my experience, but it might not be a mother ship.
Or it might be, who knows.
Clouds have always been an attraction to me since I was a little girl. Over time, I have learned to look at them differently, without trying to find shapes that my brain would identify as resembling the shapes of objects or animals (even if it still happens to me and it is often at first sight, before I start to contemplate them just for the delight of contemplating them). From years now, I focus much more on the play of light and contrast that "gives consistency" to the clouds and makes them
seem much more (though I don't know how exactly) than what I thought they were before, just water vapour and eventual rain bearers.
Anyway, for a long time, since I have a very, very large view on sky from home, I have the feeling that some electromagnetism force could be able to
shape clouds in certain manner, especially when they are here and there as spots on the background of the sky (whether it is blue or not, but more often evident when it is blue) and arranged in a lateral line at the same depth. Because, to me, and I've noticing this a million times, these clouds often seem to have the almost same shape, like it is a
repetiting shape almost identical from one cloud to the next (as long as they seem to be on the same depth line from the observer point of view and that they are not too far to the right and left of my vision).
It looks as a pattern that repeats itself in a specific area, as subjected to some
force there; as I have often found myself turned towards the sky, just looking without expectation, I notice that the shape can and does seem to change for each of the clouds present on the same depth line. Also sometimes, on two or three different depth lines (further and further away from the viewer, when the clouds are placed on several horizontal lines which continue towards the horizon with the size of the clouds decreasing due to the distance), the shapes look the same but are just smaller the further the cloud depth line is from the viewer.
All this without forgetting the Henrik Svensmark's work:
For French readers, there is this Best Of Web on fr.sott.net:
Balade dans les nuages avec le physicien Svensmark — MàJ : Le rayonnement cosmique contribue à la formation des nuages
Also this from a French source, the very same used to update the Sott article:
The CLOUD experiment
Henrik Svensmark's work caught the attention of Jasper Kirkby, a researcher at CERN, the world's leading particle physics laboratory based in Geneva, in 2006. Jasper Kirkby is behind an experiment using a CERN particle accelerator to study the possible link between galactic cosmic rays and cloud formation in the laboratory. The experiment, called CLOUD [6], uses a fog chamber powered by the PS (Proton Synchrotron), an artificial source of cosmic rays that simulates natural conditions. A beam of particles is sent into a reaction chamber; its effects on aerosol production are then analysed.
Then,
An experimental study by H. Svensmark
et al (Technical University of Denmark)
published on 19 December 2017 in the journal
Nature Communication shows that cosmic radiation contributes strongly to the formation of clouds influencing the climate of our planet.
This study was discussed five years ago on Watts Up With That? (as well as it is dicussed in French in the link provided above about the French source used for updating the Sott article):
New paper: The missing link between cosmic rays, clouds, and climate change on Earth
"Instead of seeing clouds as a consequence of the climate, it is actually about showing that the climate derives from the clouds, because
the clouds receive their orders from the stars." ~ Svensmark,
The Chilling Stars, written with Nigel Calder.
Also this video with Henrik Svensmark & Jacob Svensmark in which they "discuss the connection between cosmic rays, clouds and climate" :
Finally, some of the crop circles are apparently fields of wheat (most often?) shaped by a "force" (electromagnetic one and/or cosmic radiation, or else?) to obtain this or that shape,
deliberately. Why
not clouds? For me, the question remains open, whether that would be deliberate or not—note that it could be both, we don't know: here deliberate and elsewhere not deliberate. Just a thought FWIW.
But there too, visual ‘magic’ can be seen sometimes. The beauty of it.
