Help please.

Can anyone suggest functions for:

A pipe (i.e. a cylinder with a hole running through it and a configurable
wall-thickness).

A brain-like effect.

Also, with a function like:
(f_hex_x(x,y,z,1) - 2/3)*-1
how would I go about wrapping this around a sphere? (if such a thing can be
done).

pigment{rgb<1-C/8R/2C/8>}}#local V=V-128/B;#end#local B=B*2;#local C=C+1;#
end#end A(234,1,0,2)A(85,1,0,1)A(81,1,0,0)light_source{-5 1}//Tom Melly
