It looks great, but it's not fluid physics. It looks like an animation triggered on movement but it's the same every time, and the liquid isn't simulated. I think there's a wind down and the animation is restarted by more movement. Again, looks sick, probably not fluid physics. And everyone hasn't complained of a sudden 30% FPS drop when players in the server are wearing the suit :)
