My gravatar was made with the following Mathematica code:

Graphics3D[{
  GrayLevel[.3], Specularity[White, 15],
  Lighting -> {{"Directional", 
     RGBColor[.3, .3, .4], {{5, 5, 10}, {5, 5, 0}}},
    {"Point", Black, {12, 3, 15}},  
    {"Point", White, {12, 3, 4}}},
  KnotData[{"TorusKnot", {2, 5}}, "ImageData"]}, 
 ViewVector -> {{0, 0, 5}, {0, 0, 0}}, Boxed -> False, 
 Background -> None, Axes -> False, ImageSize -> 1000]

@kuba Removed the support folder, it worked, so replaced it. Removed init.m, it worked, so replaced it. Then a binary split test - remove half the file, if it works, then the problem is in the other half; repeat until the problem is isolated. Only took 1/2 hour :)

@ssch strange...looks like the CDF code needs to check for some of these options.

comment Can't create a simple CDF
@ssch see if it works after moving your init.m file somewhere else. Perhaps there's another setting in there which has the same effect.
