    Be sure to also look at these other Wii remote projects by the same author here. I think they are nearly equally as cool.

    Now as to why am I not writing a demo using the technology/techniques described...

    Re: Windowless 3D Content - Metaballs

    Your setup is probably fine.

    I have a few computers the demo won't run properly on. Currently I don't have a development environment setup on them to track down the problem, but I will soon.
