I might be doing something stupid, but I can't see what it is. This simple example shows that I'm trying to hide the Box, but failing. (I tried it just once, in different positions, too.) The code is a little weird, so that might be the problem...
splot1 = SphericalPlot3D[
Cos[\[Theta]], {\[Theta], 0, Pi}, {\[Phi], 0, Pi}, Mesh -> None,
Boxed -> False, PlotPoints -> 80];
aGraphicsComplex = splot1[[1]];
Graphics3D[{Boxed -> False,
Lighting -> {{"Point", RGBColor[1, .9, .9], {2, 2, 4}}},
Boxed -> False,
aGraphicsComplex /. GraphicsComplex[pts_, objs__] :>
GraphicsComplex[
With[{r = 4 Sin[11 (ArcTan[#[[1]], #[[2]]] + #[[3]] )]},
{r, r, 2} #] & /@ pts, objs]}]
