For my FLA class(Fundamental of Logo Animation)...I have to make a 10 second animated logo...and I'm trying to make this sphere...that opens up(to activate inorder to burn the logo image into an enviroment)...

the only problem...is that we have to use Nurbs...and I honestly cannot figure out how to make this properly...

So I was wondering...what would be the best way to make something like this:

I am hoping not to use curves and lofting...but I can try to figure that out if I have to....or would it be better with a map????

Thanks

***sorry for the bad sketch...I just did it 10 seconds ago***
