I wondered if I could make an image similar to this one with megapov.
  This is the result:

#version Unofficial MegaPov 0.6;

global_settings { ambient_light 0 }

camera { right x location <0,5.5,-8>*1.1 look_at -y*.4 angle 35 }
light_source
{ <3.5,3.5,-2>, 1
  fade_distance 6 fade_power 2
  area_light x,y,6,6 adaptive 0 jitter orient
}
background { rgb <.7,.85,.95> }

plane
{ y,-.5
  pigment { rgb 1 }
  finish { specular .5 roughness .02 reflection .2 }
}

isosurface
{ function
  { sqrt(sqr(sqrt(sqr(x)+sqr(z))-1.5)+sqr(y))-(.3+.2*sin(8*atan2(x,z))) }
  contained_by { box { -<2,.5,2>,<2,.5,2> } }
  method 2 max_gradient 2.41 accuracy 10^-6
  pigment { rgb 0 }
  finish { specular 4 roughness .05 reflection .5 }
}
