To be more precise, the looks_like object is not literally /centered/ on 
the light source's initial location; rather, coordinates specified in 
the looks_like object are interpreted relative to the light source's 
location. (E.g. if you use "looks_like{sphere{<20,0,0>,1}}", the 
looks_like object will be 20 units off from the light source's center.)

I think that feature can be argued about; from a consistency point of 
view, I think it would make more sense if the looks_like object 
coordinates would be interpreted as absolute world coordinates (after 
all, POV-Ray uses absolute coordinates everywhere else); but I also see 
the benefits of the relative-to-light-source behaviour; and backward 
compatibility demands to keep it this way anyhow.
