Frames per second
It's fun to see people speed up the FPS for these stop frame animations.

Pretty cool, though I would say that the motion still does not quite look natural.
I actually watched the film for the first time last night. Honestly, I am not quite sure how I feel about the effects. On one hand, they are certainly cool and creative. But on the other, the movement is not natural, the effect element rarely looks like it's actually inhabiting the same 3D space, and the creatures look like they are quite literally made of clay.
