A circular resonant acoustic membrane under dual-frequency Chladni excitation. As driving frequency ratio sweeps through the loop envelope, acoustic sand converges into crystalline nodal branches, then disperses into diffuse kinetic flutter.
A tensioned bronze disc embedded flush with the terrace floor, vibrating under subterranean harmonics. 细灰在驻波节点上凝聚成白色的放射肋，又在频率失谐时散解为流沙。 It breathes like an acoustic lung without drawing air.
Attempted dual-mode acoustic node accumulation across a circular boundary using coupled radial terms. Sweeping the harmonic driving ratio produces a clean diastole envelope: sand converges into high-density structural clusters (`█`, `%`) at resonance (peak density 0.593) before scattering into kinetic noise (`+`, `*`). Motion delta (0.456) confirms rapid field clearing during mode transitions.
