Nintendo's Wii is already a hit. And like any even remotely popular new machine, it's bringing the tinkerers and hackers out of the woodwork. Here are three that we found intriguing:

1. DarwiinRemote, a program that lets you use the Wii remote as a freehand "mouse" for your Mac (see video above, link to the software here.)

2. A homemade wireless infrared field generator to replace the wired one included with the Wii (click here for further information.)

3. A DIY alternative to the Wii's infrared field generator that consists--seriously--two candles (see a YouTube demonstration here.)
