PSA: The weirdest thing I saw in a parking garage puddle

I was leaving the mall in Portland and saw this huge oil slick in a puddle on the concrete. The colors were insane, like a rainbow painting. I looked it up later and found out it's called 'thin-film interference' and the colors change based on the oil thickness. Has anyone else found art in a gross place like that?

Saw a documentary on urban puddle rainbows last week.

A whole documentary on puddle rainbows seems a bit much.
