There are few resources that provide guidance on idiomatic Ruby programming. Thus there is oppty for a focused PDF/screencast that provides an overview of the subject. This could list key idioms & provide descriptions/examples of use (within a small sample application). This would be appealing to beginning and intermediate Ruby programmers --esp. those coming from other languages.
