A link to a home-published I Ching book I hadn’t seen before. As far as I can make out from a quick look through the website (in other words – I may have this completely wrong) the book offers a new way of choosing which lines and hexagrams to read after you cast a hexagram in the usual way. It uses the Steps of Change (/zhi gua) and fan yao), but I think it determines what order these should be read in by reference to the Shao Yong square.
Anyway – it’s I Ching related, and a new approach to finding yourself among the lines. There are excerpts from the book at the site, enough for you to get a flavour of it.
