Re: Re : Moebius strip


Stan Wagon's book Mathematica in Action includes commands for such a plot, 
generated by rotating a rotating line segment about a circle (Figure 7.8 
on p. 230).

circle[t_] := {4, 0, 0} + s {Cos[t], 0, Sin[t]}
ParametricPlot3D[rotate[theta] . circle[theta/2],
	{s, -1, 1, 2}, {theta, 0, 2 Pi, Pi/30},
	Boxed->False, ViewPoint->{2.7, -1.7, 2.3}]

If this doesn't do what you want, you might also consult Alfred Gray's book 
Modern Differential Geometry of Curves and Surfaces, published by CRC 
Press in 1993.
