It looks like stress patterns in some type of plastic as seen with polarized light and filtering.
-
Looks like Bolt Strain Assay! Under polarized light producing the color pattern.
Is ytivarg that way? -
Looks like a bolt stuck into some liquid (flowing? hence the receding curve?) and then some major colour shifting has been done to get those zany colours.
It could have been flipped too as when I flip it around the ripples emenating from the bottom-right (in this original) seem more natural.

And Nell, I say "a helix" as I pronounce the h in helix. Many people don’t though and for them "an helix" sounds better. In written form… it is anyone’s game.

I remember when my spaceship trespassed the tissue of the Earth´s atmosphere… dunno what this is maybe but it triggered this memory.

I like Paul and Bodhi’s visuals. (and yes, Paul, that is a very small bolt… but the sense of movement is an illusion).
Cola and Rocketeer are on the same wavelength! Bingo Rocketeer for a speedy solution within 45 minutes (and maybe OldCola too…. As I share more detail, perhaps you can explain what’s going on here).
Iv0 said she was in vacation mode in the last puzzle… So this is a photo of plastic Maui Jim sunglasses taken through the polarizing lens of a second pair of Maui Jim sunglasses (a poor man’s polarizer).
I discovered this when playing with two polarizing sunglasses. At first I thought it was irregularities in the polarizing film of the subject lens (hence the strain ripples around the hole where the frame bolt comes through). But, the effect is only visible on the inside (i.e., there are no rainbow effects when looking from the other side to the outside lens surface). If it was polarizing defects wouldn’t it be bidirectional?
So, I was wondering if it might be thin film reflection (from the inner UV or, ironically, anti-reflective coating). Reflected light is polarized, and the rainbow image disappears if I rotate the viewing polarizer 90 degrees. The color would then be from thin film interference and the color depends on variation in film thickness (strain induced?). Perhaps the polarizing lens just helps me detect this faint reflection over the background light (especially if the two polarizers are rotated 90 degrees from each other – blocking some regular light, and most of the light that would pass through both lenses, and allowing the faint reflection to dominate).
So, what do you think?

Thanks Steve! Way to go OldCola… I think he was even closer than I was to getting it right. That is definitely strain patterns around that bolt.

🙂 I have almost the same bolts at my glasses. Were a few mm from my eyes as I scrutinized the screen…
I think that the patterns of light are produced by local bending rather than film’s thickness, but this is to be confirmed…About Helix, the "h" isn’t pronounced and the correct form would be "an helix".
There is a rule of grammar in Greek but this isn’t the place to talk about it. And you have to speak greek to understand it… -
actually, the silent "h" is from the middle english is it not? And the old rule is "an" although common usage these days is "A."
And the science of this is beyond me, all i know is that once a polarizing filter is rotated 90 degrees it sort of cancels the polarization, or skews it, if it’s a coated lens. but this is only observational and not any kind of strict series of tests. it’s still a cool abstracted photo in my vernacular at least.
