Cheated in what manner?  Only rotated each piece from a single point
instead of moving it in the appropriate curve while rotating?  I've
no idea the exact curve needed, nor how to translate it onto a sphere,
nor how to impliment that in Moray...

BtW, I noticed that the normal doesn't change position while the
pieces rotate, giving a somewhat disconcerting appearance.  How
would I fix THAT?
