Spirals and shells

Ok, I give up. I have tried several ideas and several locations. I cannot
get the graphs anything like the conchoids in the Mathematica book pages 
28 and 29 attributed to S. Dickson.  I know that the surface given in 
spherical coordinates as
     \rho = (\phi)^{5/4} \sin(\theta)
will give a type of surface, but nothing like what we have here.  Does 
anyone have a clue as to some parameters to try, or where to look. I am
also interested in the plot of the Klein bottle, if anyone can give me 
a hint there.

All help will be appreciated.
