It is a fully functional method of encrypting a seed phrase. Each glyph represents one letter of a seed word. The value of the glyphs remains arbitrary until they are assigned a letter by the user based on a seed phrase they have generated. Once assigned, the letters are stamped into the custom seed plate in a scrambled order, each matching its associated glyph. The painting is the key that decrypts the order of the letters, and thus the seed phrase.
Since the letters are scrambled on the seed plate, the words are unrecognizable. This provides additional security, since anyone finding the seed plate would have a hard time decrypting it without the painting. If one chose to use two of the custom seed plates to encrypt a 24 word seed phrase, 12 words on each plate, it would be impossible to crack without both of the plates and the painting. Anyone looking at the painting would not be able to decrypt it without the seed plate. In order to decrypt the seed phrase, one needs both the painting and the seed plate, making this a type of seed XOR.
If the seed plate is used to encrypt an address that contains bitcoin, it must of course still be securely hidden. What is interesting, is that the painting itself can be displayed publicly, and without knowing what value the glyphs have been assigned, the chance of someone cracking a seed phrase that has been encrypted to it is the same as randomly guessing any 128-bit private key.
