Wiiewer
From WiiLi
Wiiewer is a very simple Python script that plots the motion sensor data. I found WMD very powerful but also very difficult to modify and adapt. Wiiewer is just a short example that you can reuse for your own purposes.

[edit] With camera tracking
I kinda hacked around a bit with the above to work with the IR camera as well. It's horrible code, I know, but it does work.
