Grass and mud is quite easy to make, at least if you want it at distance, a bmp containing random green colours of different shades will look pretty much like grass. Anything where the details are too small to be spotted can be made this way. But if you want close distance grass, just take a camera, so far it seems to be the best way.
By the way, have worked a bit with some textures, and I think my wood generation is pretty good, but there is room for improvements, as always.
