This is Hacker News. I can't think of a better way of someone "hacking" something (i.e. using cracked glass in a novel way) to create something new, unexpected, and incredible.
I think this is probably the best idiomatic example of the type of story that I think belongs on HN that I've seen in quite some time.
As an artist, this isn't incredible. Arranging lights/darks to copy a photo is high-school tier. Money for food + shelter + materials and I could do this in a month, as with anyone who can copy a black and white photo.
