Abstract (for part I and II)
We start by defining basic spinning from a knot to a knotted sphere, defined by E.Artin in 1925.
We describe a work of Zeeman and Epstein, 1960, and construct a twist spinning of Zeeman 1965.
In the more recent developments we follow the survey paper by G.Friedman, 2004, and describe our recent results on twisted spinning of 3-valent graphs.
