Wiimote Project

This question may be in the wrong forum, and it may have been answered a ton of times, but I am curious and asking anyways. I recently saw the youtube videos about this, and thought it looked amazing! All of the projects. I would love to use them! This is exactly what I need to know:

What I can connect my WiiMote to the computer with.
Examples of the hardware I can use to do this.
What software is nessecary in addition to the hardware to do this (and does the only software I need come with the hardware)

Keep in mind that I do already know that I need the Visual Basic C++, or C#, (I'll look it up again when I get that far) and I know where to get it. Thank you very much!

you dont necessarily need blue soliel. there are other bluetooth stacks that you can use.

you can even use the default drivers on some adapters

you also might need a light pen, which consists of some sort of container, an IR led preferably 100ma, a momentary switch and a power source.

most LEDs of the IR nature has a forward voltage of 1.2 - 1.8 volts so you can just strap it right to a AA, AAA or N type battery. any more power, or more LEDs you need a resistor. there are many pen schematics laying around though.
