The first one was on the same height. This one just looked better when I 
lowered the gravity well, so call it artistic license...  ;o)

I am not sure the actual aim here is achievable: I want it to resemble the 
POV-Ray logo (or at least a "P") be mathematically correct (of which I know 
0) and still look good.

Any help will be appreciated.
