Manku Poru

Manku Poru brings the mesmerizing science of Chladni figures to your fingertips. Tap a frequency, watch a field of sand grains migrate to the nodal lines of a vibrating plate, and reveal the hidden geometry of acoustic resonance — all powered by a real physics engine running entirely on your device. Choose between circular and square plates, switch between free-edge and clamped-edge boundary conditions, and dial in any frequency from 40 to 2000 Hz. Each resonant mode produces a distinct, mathematically precise pattern — from simple two-line crosses to intricate lattice geometries. Hit SWEEP to scan through frequencies automatically and watch the sand field transform in real time. Capture your favourite figures and build a personal gallery. Each saved pattern can be named, revisited, and loaded back into the lab. Attach a photo of a real-world sand-plate experiment alongside the computed result to compare the mathematics with the physical world. Manku Poru is built for curious minds — students, educators, artists, and anyone captivated by the beauty hidden inside sound. No accounts, no internet required, no ads — just pure on-device science you can explore at your own pace.
