%clay vane
From Just Solve the File Format Problem
The %clay vane is part of the Urbit system, and like everything else in it (such as Hoon and Nock) it is pretty-near incomprehensible to anybody not well versed in its particular concepts, and perhaps politically-incorrect to try to understand due to the odd politics of its creator (which spur boycotts of any conference that lets him speak). It is the filesystem of the Urbit virtual machine, and is capable of being mounted in a Unix-style system.
