Man, I just found this video on youtube and the 3D effect is absolutely amazing... imagine playing a 3D shooting game with that! Furthermore, the effect can be done with very low cost as demonstrated in the video...

here is the video

Whoa! That is absolutely stunning! I wish I had a wii!
 
I imagine there is a good application for this in medical training, and many other fields.
 
Welcome to the 21st century. People have been doing this long before the wii came out with simple hobby grade sensors. I personally like the "write anywhere" wii remote hack better though.

To do what Johnny Chung Lee does in the video, you don't need a Wii... just the Wiimote.

You also need the light bar off the wii console (or at least a couple of LED's).

Yep... infrared-LEDs... available at Radio Shack (http://www.radioshack.com/product/index.jsp?productId=2062565)... or in bulk at DealExtreme (http://www.dealextreme.com/details.dx/sku.2399). The Radio Shack ones are better, but more expensive.

..and, of course, you'll need a bluetooth-adapter connected to a computer running software that interprets and processes the Wiimote sensor values. (By the way, the Wiimote also has a 3-axis accelerometer... which of course doesn't need any IR sources. I'm waiting for the Gyroscope attachment.)The point is one doesn't need the [expensive and possibly hard to find] Wii console.[By the way, you can achieve similar effects with a [modified] webcam and an IR-led.
You have to filter out the visible light reaching the webcam... and possibly remove the IR filter.
The advantage of using the Wiimote is that it has a dedicated onboard processor which tracks up to 4 points at about 100fps.]
