Put your wii remote to a greater use.

The following is a nice TED talk which demonstrates an wii remote hacking idea which extends the functionality beyond gaming. The speaker developed a freely downloadable software (his website) which uses the infrared sensing capabilities of the wii. In the talk he demonstrates few applications of the basic idea. He shows a infrared pen which uses the screen projection as white board. In another application, with two infrared devices, he creates two touch points which can be used as a multi-touch interface. But the best part is that the infrared device when attached to the head can be used as a head tracking device. The 3D projection keeps changing according to the position of the viewer head.

Operate your computer with wii controller

Lifehacker is running an article on how one can operate the computer with a wii controller.  This technique exploits the bluetooth capabilties of the wii controller (including the balance board of wii fit). Once you have a wii console, all you need is a PC/laptop with a bluetooth capability. If you do not have on in-built you can purchase an external bluetooh adapter/dongle for almost nothing. 

Pairing up of the wii controller with the computer is more or less like pairing any other bluetooth device(Read the lifehacker article for detailed info). Once the device is paired up, you need to use a software named "GlovePIE". This software is used to map the signals given by the wii controller into computer movements like mouse buttons and arrow keys.

What else ? Sit back and control you pc with your wii controller.
