Don't you just hate that swamp biome... 'water?' Wouldn't you rather have smooth, realistic water colors? uWater changes the color of water using an algorithm to check for the temperature and humidity of each block of water, then converts it to a coordinate to be used with an image. That image contains the color that the water should be in that climate. Put simply, it makes water, grass, and leaves look great and adds to the visual atmosphere of Minecraft. You may turn off grass, leaves, and/or water coloring via the configuration file, as well.
v1.0 [NEW] - Added grass and leaf biome coloring.
