Shortly after the last post, I discovered some amazing videos by Mark Stock displaying simulations of Rayleigh-Taylor instabilities in fluids. The Rayleigh-Taylor instability arises when two fluids sit on top of each other, with the one on the top being denser than the one on the bottom. This is of course an unstable situation, and small inhomogeneities in the interface develop into turbulent structures when the fluids start mixing. The wikipedia article above shows a beautiful picture of the Crab Nebula, where this phenomenon creates awesome fingers of gas.
Here are two of Mark's videos. Watch them full screen! You can check his youtube channel here.
