Hello, I have seen interesting graphical conversion diagram in Genk (Belgium). Some photos here - http://www.saulespulkstenis.lv/genk-bifilar/
If you look closer at the last photo, you can see that with a little practice reading the time from moonlight shadow could be really easy - just select the appropriate circle corresponding to the Lunar phase (Arabic numerals) and then look for the closest intersection with those off-set circle lines (Roman numbers show the time).
