Each turn of the head resulted in something new, and it was exciting to see the piece come alive with a closer look and a turn of the head.   He also, it appears deliberately used blown glass for this piece, and a well-rounded, smooth piece at that.  It is pretty difficult to blow glass and shape it into an almost perfect sphere, and I find it interesting that Statom chose to leave only a small bubble instead of blowing the glass out all the way into a sphere.
