Wii, Wpf, and Binding
Having done minimal WPF work myself due to lack of time, I found an interesting thing on Rudi Grobler's post regarding the Wiimote and WPF.
Rudi points out that with WPF, you can bind by implementing the INotifyPropertyChanged interface. When a property changes, the UI updates too. Rudi only modified the WiimoteLib for one IR point, but extending it to all 4 that are currently supported wouldn't be too much additional work.
