Mathematica apprentice

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]

comment professionalize/optimize my code that calls a function
Not sure what you're trying to optimize? The function? Or "the code that calls the function"?

comment Mathematica Application in Real Life
So you're looking for non-scientific examples of the use of Mathematica in people's "daily life"? There are plenty of examples on this and other sites. But I don't see where your "expert levels" and code brevity concerns come in to the question...?

comment How can I add any points in Manipulate?
(f1[0.5],... yet you have f1[x_, y_] ...? Points such as Point[{2, -3}] are easily added to the Epilog expression...

Buy a nice display instead! (And keyboard and mouse too...:) As you can tell, I'm just jealous really...

comment How to parse a .css file generated by Mathematica? modify values, add some values
Hi - no I know very little about CSS, except that it cascades (inherits). But your question isn't clear - what are the different selectors for width. What is overriding what? And your 'parser' won't work on all CSS files (they can be very complex- even containing image data). I wonder why Mathematica doesn't parse CSS files?

Like it. Next time let's hope the questioner asks for Seurat or Mondrian or Vaserely... :)

Looks nice - the sky is a problem as you say, just not very van-goghy to start with .. It probably needs some of your hedcut-style texturing...
