Recent developments in my fluid physics project include gravity, and directional  vectors with user-specifiable magnitude. It is now, for the first time, starting to look like a fluid. Performnce is so far good, and I am very confident that I will end up with something worth releasing at the end of this. 

I still need to do some more physics code, and then add materials and shaders to the metablobs. I have also considerd adding multi-threading support to the project, and creating a seperate thread just for the fluid dynamics. Since almost all machines are multicore now, this should provide a significant performance boost for almost every user.
