I would be VERY grateful for advice.  Basically I want to
plot an x,y trajectory on the surface of a sphere.  The data
I have are in the following form:

x: a vector (N) in [-200,200] 
y: a vector (N) in [-200,200]

NB these vectors are toroidal in the sense that -201 maps to
199.

What I want:

plot these trajectories on a sphere of fixed radius (ie non
deformed). 

Simple question:  If all this is too much, just tell me how
to plot a line on the surface of a sphere!

Thanks!

Thanks
