Easy. Change the long function to simply:

NORMAL_STATE::ChooseJointType( )
{ return( TEAPOT );}

And re-compile.

It was Nick's favourite screensaver because it had this Easter egg. From memory, I think that the screensaver went slower when it did a teapot, probably because they're harder to render. So making it all teapots could make it less responsive and not immediately go away when you move the mouse or press a key.
