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 Fastest way to concatenate many text files in a given directory
If you have Unix tools available, just cat *.txt > hugefile.txt is sufficient to join the files.

comment Google speech API . Speech to text recognition with Mathematica
I've used the Dictation feature (Mac OS X) to input plain text. But try saying "plot the sine of x" to Mathematica and you'll get "plot the sign of eggs", "cosine" looks for "coastline", and "pi" looks for "pie". You end up spending more time correcting it than getting anything done.

What platform/version are you on? Works fine for me on Mac OS X Mathematica version 9.0.1.

comment Manipulating horizontal and vertical 'guidelines'
The rounding to 2 was only to make you notice Round. :) I had thought of decreasing the rounding strength as it approached the plotted line, but I got distracted...

no problems here - the top of the "Test" text aligns with the top of the left plot.

comment Animate crashes Mathematica
The message from Mathematica (replacing Animate with Table) is "Recursion limit exceeded (1024 or something)", but since I don't really understand recursion I can't see where it goes wrong...

You start your animation with n = 0. Perhaps that's what's wrong...
