It's by a couple woodworkers who have been learning about fundamental design principles that used to be used extensively before the introduction of tape measures, calipers and tools that have served to drive design almost entirely into imperial or metric measurement systems. I don't think it can address all of it (e.g. kerning), but some of the things I saw in the guide relate directly (1.2x/1.5x spacing, typeface sized in multiples, etc. I found it fascinating. They have a couple other books about it now too.
