Thanks, indeed the caustics are quite nice. The ior of the interior
is 1.5. 
I made the scene arangement some month but I remember that
the earth/light position was chosen so that much light can
pass through the oceans and will not get cought by solid earth.
Actually it is two spheres. One for the soil and one refractive for the
water. Using just one sphere produced problems with photons and shadows
then. So I took two seperate spheres with the soil sphere beeing the
slightly larger one.
