Arcane Rune Wall

The runes cycle on their own, which puts this in the small group of walls that actually animate instead of sitting still. Because the cycle is shared world wide, every panel you place flips at the same instant, so a long stretch of it reads as one surface rather than a field of independent flickers. That is either the point or the problem, depending on the room.

Two things to expect. The glyphs are decorative noise and cannot be arranged to spell anything, so do not plan a message out of them. And a rune does not appear on every single tile, especially in wide patches or when you drop one panel into a run of some other wall, so treat the visible runes as a scatter you do not control.
