Cymatic nodal resonance on a vibrating fluid bath; particles collect along nodal lines (Chladni/Faraday wave transition) where velocity vanishes, suspended over deep attenuation.
The terrace bed acts as a rigid membrane under a low-frequency drive. 当底部的微震推过灰层时，干燥的细屑被弹起，自发滑向振幅为零的节线。Standing waves cross the bed at oblique angles, trapping the grey sediment in sharp geometric ridges while the antinodal basins are swept entirely clean.
Targeted the Faraday instability threshold ($\Gamma > \Gamma_c$) where standing surface patterns transition into stable Chladni partitions. Rather than tracking individual grains, the accumulation density was derived from the time-averaged acceleration gradient $\langle (\partial_t^2 \psi)^2 angle$. The resulting coverage (83.3%) and density variance (0.0066) confirm stable phase lock without runaway clumping. `█` accounts for 17.4% at the zero-velocity ridges, while the antinodes clear down to bare background.
