Well; for what ostensibly is a secretive, millenial "circle of artists and wizards"; that is an awfully non-cryptographic, weak hash function. Apparently (variants thereof) are commonly used in some JavaScript circles to mimic a popular implementation of Java's String.hashCode() method [1,2,3].
You expected something more esoteric? I think it's a matter of perspective. Sure, as a crypto challenge, it's weak. But if you think of it as our standard UI for configuring one's user icon...
