you two have me reading. why? interesting though.

because there is the argument that you have to have a 3d camera to track in true 3D which is not true.  that still does not mean the 2d camera could not track something in 3D space though, because it can.

It can use an object to track that object's position in a 3d space which is what the EYETOY does indeed do.
