For example when he released the book "why's poignant guide to ruby" (http://mislav.uniqpath.com/poignant-guide/) teaching the Ruby programming language, he released a soundtrack with it as well! Here's my favourite song from that: https://soundcloud.com/wondible/chapter-2-this-book-is-made
Hopefully the primer I'm writing will help for those new to the person that is Why the Lucky Stiff.
A lot of his Ruby code was fuckin' genius, too.
