Ha! Old threads never die, they just hibernate for a year.
I doubt anyone will get this although it will be plain with the explanation. I have never seen this common object viewed this way and was quite surprised how it turned out. Look at the colours in the enlargement - they have a name that we all recognise from a young age.
Any guesses?

Correct but you need to explain the first photo and the word we learnt when we were young that explains it.

Well, it's some kind of refraction creating a rainbow like effect. Can't be ice on the lens because it's summer where you are.
