If you don't want to study a whole new language or giant textbook, you might get some intellectual mileage from checking out the Reactive Extensions for .NET, which is an extremely slick implementation of functional reactive programming in C#, and implementing some simple applications like a game or two with it. If you don't know anything about FRP, you might find it somewhat mind-expanding. It focuses on treating input as a continuous, manipulable stream of events. It integrates rather elegantly with C#'s functional libraries and interfaces. (This is assuming you have a fair amount of experience with C#, or else you'll probably spend more time learning the language than FRP.) http://msdn.microsoft.com/en-us/devlabs/ee794896.aspx http://msdn.microsoft.com/en-us/devlabs/ee794896.aspx
