No mathematical tricks though, in the past, I temporarily added a 
brightly colored sphere object to the scene and set my cameras Look_At 
parameter to the sphere. Then I just moved the sphere around until I got 
the "view" I wanted... When I'm ready to render, just remove the 
sphere... YMMV... :)
