This is my Nintendo Wii Controlled Smart Home. Using the Wii-Mote and my Nintendo Wii, I have an onscreen Flash User Interface that lets me control the following aspects of my home: Lights, Thermostat, Security Camera, Music Playback, Cable DVR, and more.
A joystick emulation application (GlovePIE) allows Nintendo Wii Hackers to use the bluetooth in their wii-motes to control the mouse cursor in Windows XP.
