Sadly not had much time for Pov-Ray for a while, but played this weekend.

Inspiration from my friend Julie's recent dandelion photos plus And's 
recent polynomial based "polygon to circle loft" work. Dandelion head is 
the difference of two 6th order polynomials, copied, variously rotated 
and their union cut to the shell of a sphere.
