Forget human faces, one of the hardest things to do in game development is get water right. It's fluid, it's messy, it's always been a problem for games to simulate the wet stuff accurately. But hey, it's 2013, so let's see how things are coming along.

NeoGAF user -SD- has shared a collection of videos highlighting the latest in fluid technology. Running using Nvidia's PhysX tech, they were put together for this year's SIGGRAPH conference, an annual event for computer visual effects.

Being a stage demo, this is a little beyond what's actually capable in a game, but give it a year or two, and it should be ready for primetime, especially on a new generation of consoles.
