Interesting write-up.

I have deep respect for practical effects and the CG variety. I like how you used the fluid dynamics as a simulation environment, I imagine the motion is extremely similar to microgravity, viscosity notwithstanding.

Curious to ask what your opinion of the post-capture refocus abilities of Lytro Cinema cameras - https://www.lytro.com/cinema

I've heard but not verified that it enables even finer-grained control in integrating shots like the ones you worked on. Apparently the refocus ability allows CG to pick out the finest elements without any green screen "bleed" or artifacts.

Is this true? I am not in the field myself, but have an interest in it, so I'd love to hear what you think of that tech.
