Not sure if you are aware John, but...

the Wii remote uses two main, but separate, systems to detect the movement and positioning of the Wiimote.

The LED bar that goes either above or below the TV is simply there to project two high-intensity spots for the Wiimote's IR sensor to detect. These two dots are used to determine the distance away from the screen, the up/down/left/right and wrist rotation when pointing at the screen.

The other mode is by the use of three Analog Devices ADXL330 accelerometers which detect the movement of the Wiimote in free space. In this mode, the Wiimote does not need to be "looking" at the sensor bar at all, the movement is being detected by these accelerometers and bluetoothed (the method of communication between the Wiimote and the Wii base unit) back to the base unit.

This is how the Wiimote can be used despite not being in perfect alignment with the TV. The only downside is that sometimes bright lights / sunlight can affect the quality of the pointing device.

Hope this helps.
