The following should yield a hemisphere: - 2 Pi/5 \le \[Phi] \le 3 Pi/

SphericalPlot3D[UnitStep[{Sin[\[Phi]] Sin[\[Theta]], Cos[\[Phi]] Sin[\
Cos[\[Theta]]}.{Cos[2 Pi/5], Sin[2 Pi/5], 0}],
{\[Phi], 0, 2 Pi}, {\[Theta], 0, Pi}]

What I get, on my Mac, OS 10.7.4, looks like a helmet. I could send
you a copy of the plot by e-mail.

I have low expectations for Mathematica, but they just bottomed out.
