Fluid Motion Simulations and Artwork. When a droplet falls into shallow water, it creates a crown or "coronet". This droplet simulation was calculated using Smoothed Particle Hydrodynamics (SPH). SPH is one of the most impressive-looking fluid simulation techniques.

Sand Pendulum. Phase of Sound #09 "Interference Wave" Sound and Salt. Resonance. Oscillon. Astonishingly, oscillons of opposite phase will attract over short distances and form 'bonded' pairs. Oscillons of like phase repel. Oscillons have been observed forming 'molecule' like structures and long chains. In comparison, solitons do not form bound states. Stable interacting localized waves with subharmonic response were discovered and named oscillons at The University of Texas at Austin.
Solitary bursts had been reported earlier in a quasi-two-dimensional grain layer at the University of Paris, but these transient events were unstable and no bonding interaction or subharmonic response was reported. The cause of this phenomenon is currently under debate; the most likely connection is with the mathematical theory of chaos and may give insights into the way patterns in sand form. The experimental procedure is similar to that used to form Chladni figures of sand on a vibrating plate. Nonlinear electrostatic oscillations on a plasma boundary can also appear in the form of oscillons. WSM = Wave Structure of Matter. Cymatics - Bringing Matter To Life With Sound (Part 3 of 3)
