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.
