+[Mod] Animated Fluids [animatedfluids]

+Description:
+This mod gives an animated texture to water and lava. Each frame moves the texture one pixel for a total of 16 frames. The speed of the flow animation is based on the viscosity of the fluid. It's only 13 lines of code! (plus textures)
+It only animates flowing fluid, not a static body of fluid.
