Oh yeah, there are not many options nowadays. I know this one which is offered by Coursera: "Functional Programming Principles in Scala". I didn't take it, but it should be helpful if one want to explore that "weird wizardry functional stuff" -and discover that there is not much wizardry at all. Oh and as others stated above, it is not that difficult once you really dive in :)
