I thought I saw QR-codes but it looked like a checker board pattern. Well, its got squares. you could do a painting with qr-codes. We don't know if she is telling the truth. How do we know if theres bitcoins in it. she could have painted on top of a paper bitcoin with public and private keys addresses. Maybe that will show up in xrays. cryptoart seems to look like paper bitcoin wallet, public and private keys in plain view. I don't think the artwork itself has any bitcoin info in it.

I see different amounts of flames around the edges. could be a form of counting system, maybe bar codes
