Because Mike, I want to complain bitterly to you in person for giving me those sleepless nights back in 2008, when you guys had the Hard Hat Challenges...

Actually, I saw the challenge yesterday morning for the first time. I read the nice clues above fromFridjon (Thanks btw...), and I immediately associated everything to the good old Amiga-days, when we used to make demos with nice vector graphics in them...
These numbers just had to be vectors. I figured that the groups of four numbers must be "Distance" (the length of the vector), a "Point" (X and Y coords) and "Direction" (the angle). The problem was just which number was what? The last number was the only
one in each group that was larger than 0, so that had to be the length. The third number spanned from negative to positive numbers, so I guessed that had to be the angle. That left the coordinates to number one and two.
Then I created a small C# program that would draw all these vectors (using what's left of my old trigonometry knowledge from the scene). Of course nothing showed up... But then I thought about "the wrong direction", so I animated a rotation on every vector,
and after some "trial and horror" a text magically appeared in front of me... "ASK THE BRAIN ABOUT XYZZY". So I did...

Just let me know... Am I on the wrong track?

This challenge was not easy! The winner should receive two shirts.
