@Eisbär: not really, although that song crossed my mind multiple times while I was busy with this puzzle. It is a type that exists already for a longer time, and I used it before in my '5-years-portal-anniversary-puzzle' too (id: 0001T3). But that puzzle is still on your list of unsolved puzzles. :-)

Inspired by Dream Theater's "The shattered fortress"? :-D
