That's a 12-word seed. Well, a public test one, never use it.
SeedCraft keeps the words of a seed as the order of some objects: beads on a necklace, bricks, stickers, photos in an album. You read it back with the web tool, or by hand with a pencil and a printed table, no computer needed.
Why: a seed written in words or as a QR code is obvious to anyone who finds it. A necklace in a jewelry box isn't.
What it isn't: encryption. The "dictionary" (which piece means which number) is discretion, not a secret key, and the spec says so. If you use a bag to pick pieces at random, they all have to be the same shape, size and weight. Otherwise, use dice.
v1.0.1 is out: the format is frozen, there's a by-hand manual, and the web tool comes in 9 languages.

It came out of NDS-Signer, but it works with any wallet.
