Circles on sphere

Hi guys.

I'm trying to make two ellipses on a sphere, basically a head and eyes. And then I would like to manipulate the sphere with the help of osc and an accelerometer. I would like the 'eyes' rotation centre to be the centre of the sphere, so I'd like them to rotate along with the sphere. I don't want the eyes to be normal to surface of sphere. I would actually like them to start 'facing the screen' and only rotate as the sphere rotates.

I will hide the sphere eventually so what I'm aiming for in the end are two eyes.

I have a few ideas of how to start, but I would appreciate any insights what might be the fastest to get two circles on a sphere and get them moving with it if someone's done something similar. Would doing 2 points for position be a good start?
