I finally finished the revisions to Book 1. It (was) posted on the main page of lengtat.us.
I have also been working on Book 2 this week. It explains the Corners First Method that I use when I want to solve the cube that way.
The corners first method is my preferred way to solve the 2x2x2 cube, since it is all corners and no edges. I also use it to solve the 4x4x4. In order to solve the middle layer edges of the 4x4x4 and the 4 center sections at the end I also use Through the Door — Bam!
