How would I rotate a sphere so that a certain point on the sphere would
point at location<x,y,z>?

--
 camera{location<0,0.25,-2> look_at 0.5*y} #declare
T=texture{pigment{crackle scale 0.5 rotate 90 turbulence 0.75 color_map{[0
rgb 1][0.05 rgb 1][0.1 rgb<1,0.25,1>][0.25 rgbf 1][1 rgbf 1]}}
finish{ambient 1}} #declare c=difference{torus{0.5,0.1
rotate -90*x}box{<0.7,0,0.2>,<-0.7,-0.7,-0.2>}}  merge{object{c
translate<0.5,0.5,0>} object{c translate<-0.5,0.5,0>}
cylinder{<1,0.5,0>,<1,0,0>,0.1} cylinder{<-1,0.5,0>,<-1,0,0>,0.1}
cylinder{0.5*y,0,0.1} texture{T}}
