The demonstration program (see attachment below) was written in C/C++ and uses the Dark GDK for DirectX 9 graphics, and the ManyMouse API to get input from the three mice.  The user controls a spaceship in 3D in position or rate mode with the Nautamouse prototype.    

Here is a FRAPS grab of the demo program.

Here is a video of the prototype in use.
