Back when Borders was still around I stumbled upon a Functional Reactive Programming book by Paul Hudak. To this day it's still one of my favorites. If you know Haskell and don't want to learn Scala, you might enjoy this as an alternative to the course. The book is called The Haskell School of Expression: Learning Functional Programming through Multimedia.

As far as I know, Hudak has updated and renamed his book to The Haskell School of Music, and it's available for free from the Yale Haskell Group's website here: http://haskell.cs.yale.edu/?post_type=publication&p=112

The book is a really awesome way to learn Haskell. However, very little of it is actually about FRP; there's one section about GUIs using FRP, and it doesn't go very much in depth.

Pretty sure that's just a different book by the same author. "Updating" a book on graphics to make it about music instead doesn't sound like a second edition kind of maneuver.

... especially true for one dealing with an "immutable" programming language
