Here are the relevant objects :

#declare LiPo = <-2000, 250, 0>;

light_source { LiPo White }

disc { 0, y, 100 pigment { cylindrical pigment_map { [ 0 rgb 1 ] [ 0.5 rgb <1,
1, 0.5> ] [ 1 rgbt 1 ] }
} finish { ambient 1 } rotate z*90 translate LiPo }

sphere { LiPo, 100 hollow pigment { Clear } interior { media { scattering { 1, 1
} density { spherical density_map { [ 0 rgb 1 ] [ 0.25 rgbt <1, 1, 0.5, 0.5> ] [
1 rgbt 1 ] } } } } }

camera { location <2, 0.05, 0> right x*16/9 look_at <0, 0.2, 0> }

I have enabled radiosity with media on for this scene.
