The camera location is the offset from the individual triangles. If you 
had a positive z value you'd shoot the rays the opposite way from the 
mesh, reversing the triangle normals and probably not getting anything 
exciting. I've experimented with sliding the location around the XY 
plane but it doesn't seem to have any cool effects like slanting the 
image or anything.
