[1.5.1] FiniteLiquid v5.92 [experimental Forge version ] [ stable ModLoader version]

 The water physics in Minecraft have always bugged me. But I understand why it was put in place the way it is. But I've developed an alternative, more realistic, water physics system for Minecraft. Now with FiniteLiquid installed, all of the water created by the map generator will be replaced.
     Oceans have an 'infinite' amount of water, this is necessary for your computer to run it. Any water disconnected from the ocean and low in mass will be finite and react to changes in volume. If you break a border wall inbetween the lake and a cave, the lake will flood downward and drain out.
     I've also developed pipes and pumps to interact with the liquid further. You can place pipes that will suck up liquid when the pump is activated; with a right click or redstone input.
     Sponges are randomly generated on the map. They will appear underwater. They absorb a lot of water if the sponge is placed below it and they can be squeezed dry.
     Water grates allow water to pass through, they can be 'closed off' with a redstone input.
     Water sensor blocks activate connected redstone when a neighboring block is finite liquid.

     Methane will generate underground. Methane either catches on fire or explodes

Wow, this page has gotten messy. I'm going to have to move to a wiki.

Start with a new map, it doesn't replace the old water in your old maps.
It will lag a lot when chunks are generating, but if you sit in one area for awhile until everything loads you will be fine.
