I probably already learned about this in the class in the past, already forgot though.

try edit photos to see which one I like if I want to mod the dial:

1. empty inner is pretty good, but then why not just go buy ML08 da Murph and be done with it?
2. only 15-18-21-24 inner: look unbalance
3. even-numbered inner: look really good, easier to read

hmm might do (3) if/when I commit
