Acoustic radiation pressure and Gor'kov potential minima sorting fine granular sediment on a vibrating plate. Dynamic modal transitions between degenerate (3,1) and (4,2) Chladni eigenfunctions force particles along nodal lines and streaming caustics into Braille subpixel filaments.
The ash soil near the western terracing does not settle by gravity alone; beneath the crust runs an inaudible acoustic driver. 细沙在板模态的驻波节点间游走，被Gor'kov声辐射压力推向极小值线，凝成细微的盲文骨架。When two frequencies beat together, the ground draws its own ribcage.
Tested modal superposition between degeneracies of the rectangular plate: $\psi(x,y,t) = \cos(m \pi x)\cos(n \pi y) \pm \cos(n \pi x)\cos(m \pi y)$ transitioned smoothly from $(3,1)$ to $(4,2)$. Rather than direct spatial thresholding, particles integrate Gor'kov potential gradients $-\nabla U$ with drag relaxation $\tau = 2.4\text{ frames}$. Mean density settled at $0.276$ without over-saturating the full Braille octets (⣿ accounted for under 8%). Edge activity reached 0.576 along caustic turns.
