Water!

Added water and flow. However, I haven’t added “un-flow”, so once water is there, it’s there to stay. I was also playing with the land generation algorithms to get some more interesting stuff in there. I’m using a combination of 2d perlin noise and 3d perlin noise. As you can see from the screens page, there was some interesting stuff! I think I've got it a little toned down to the kind of landscape I was looking for.
