Well, the more I read, the better I get at remember names of people and medical terms, etcetera.
Sometimes, I use this method as an alternative to saying the word over and over.
It is not my primary method to remembering names, which is really just using regular old memory without a given method.
However, what usually happens so far is that I can remember a given geometrical
clue to a word, say a few days later, and can then try to figure out what the word was.
So far the implications are not well understood as to what I am accomplishing.
However, no pain, no gain.
I think if you work with 2-D or 3-D geometrical things in your head a lot, it probably helps you in other ways too.
For example, I can unscramble words puzzles in the newspaper in my head without paper and pencil sometimes,
and this may be do to constantly trying to imagine stuff in my head.
