recognizability out of the problem of human-manageable long numbers. The
application is to eventually be part of a complete solution.

to break the key itself. But the key itself is also moderately spoofable,
in the sense that keys can also be visually similar ("l" instead of "1").
The question is whether it's easier to do a visual spoof with bezier

able to remember more stuff if it's split up among multiple axes.
(Assuming that the ancient paper I read on this, the George A. Miller "The
Magic Number 7 plus or minus 2" 1956 classic, is still credible).
