After some search I found only one:
But it seems clear that in this case, surface tension effects are predominant, what prevents the formation of small scale structures. The simulations didn't take surface effects into account.
Still, provided you find a fluid that satisfies the hypotheses used in the simulation (in particular negligible surface tension and viscosity, I would guess), you will get something very close to the simulation. After all, the theory of fluid dynamics is an extremely good approximation to real fluids in many situations. The picture of the Crab nebula shows that the Raleigh-Taylor instability can indeed create fractalish structures in physical situations.
