I can’t remember whether it was here or somewere else but there was a link posted to an online app that converted pictures to a series of black lines of varying width to recreate the image.
I remember seeing an example of a person’s face turned into these lines then they were painted black.
I want to have a go and fill them with epoxy on something thin then illuminate from behind. Just cannot remember what this style of art is called and where I saw the link.
I know you’ve already found what you were looking for, but I thought I might add this link - the guy wrote half-toner and “mirage” (squiggly lines/dots) photo conversion software. The mirage is a crazy way to do a photo and can look super slick if done well.
