Mathematica apprentice

My gravatar is an eternal golden braid, made with the following Mathematica code:

Graphics3D[{
  GrayLevel[.3], Specularity[White, 15],
  Lighting -> {{"Directional", 
     RGBColor[1, .5, .4], {{5, 5, 10}, {5, 5, 0}}},
    {"Point", Yellow, {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]

2d	revised	How to relate memory usage with occupied positions of SparseArrays? spelling
2d	comment	How can I detect an ellipse in a photo? Code is great, and descriptions we can learn from even greater!
2d	comment	*Telling mathematica to output instead of space for multiplication, so I can copy as plain text** or `a b // InputForm` ?
May 21	comment	Setting OperatorSubstitution to False has issues with PDF and EPS exports. Are these bugs? There are some similar problems that appear to be Mac-only...
May 21	answered	How can I detect an ellipse in a photo?
May 21	comment	Filtering the elements of an array to split them into two categories @rcollyer True enough (and where's Misery to complain about the documentation when we need him...?). But I know that some basic familiarity with Mathematica syntax is usually expected here, so I thought I'd hint as much...
May 21	comment	Filtering the elements of an array to split them into two categories It means you should have a look at the fine manual! And this as well...! ;)
May 21	comment	How do I automatically “trim” the bounding box for a Graphics3D output? Related?
May 21	revised	How to insert big list of Data in DB? how many times do I have to delete the unnecessary words at the end?!
May 21	answered	How to keep ItemSize effect when export to HTML
May 20	comment	Setting OperatorSubstitution to False has issues with PDF and EPS exports. Are these bugs? Looks more like a Mac problem (for PDF at least). I can't get other fonts to display their own operators - looks like it defaults to something else.
May 20	comment	I want to draw a graph using a weighted Adjacency matrix @Ryan I don't think you have enough reputation to upvote...
May 20	comment	I want to draw a graph using a weighted Adjacency matrix Right-click gives some alternatives, but it's complicated stuff...
May 20	comment	Unexpected error message from GraphPlot evaluation :) Cool! Although this question probably becomes 'Too localized' now... :(
May 20	comment	Unexpected error message from GraphPlot evaluation I saw no errors after deleting the 0.05 from `Line` function calls.
May 20	comment	Unexpected error message from GraphPlot evaluation Is this correct: `Line[#1, 0.05]`?
May 20	comment	I want to draw a graph using a weighted Adjacency matrix @belisarius That works well, thanks! Updated.
May 20	revised	I want to draw a graph using a weighted Adjacency matrix added 0 weight to infinity
May 20	comment	I want to draw a graph using a weighted Adjacency matrix @belisarius Ah, that would be better... :)
