Antonio has some pictures on his web site, as I recall.  He's spun a
number of spheres. Spinning, like anything else, looks easy when you
watch an expert!  It isn't, but it's something you can learn.  I spun a
bit of stuff in the way of copper bowls when I was in high school, and
the main thing I remember is the need for repeated annealing as the
copper gets work hardened.  I think that the usual "spinning aluminum"
is pretty close to pure and don't think it work hardens.
