What hides between Shadow and Light?

[ROT51]

Well... I'd like a confirmation that it is solveable before I really sit down with this. Perhaps a clue or addition. There's stuff like this that people have been trying to solve for near ten years with all kinds of common mathematical equations, codebreakers, puzzle solvers, matrixes etc.

That's hopeless.. They won't give any clues, or is it really solveable. Thomas and Jens just want to laugh at us. At this point i'd say that this puzzle is just their bad holiday joke to us, count on that.:mad:
