A friend asked me why there were only like 3 or 4 ways that people did grass. I said there are probably only so many patterns at small sizes to work with, and after that, they call begin to look similar. He told me that was bullshit, so I attempted to find a new series of marks. I would not call it game-ready, but I think I found something nice. Always good to look at the mundane tasks differently -- that's how we really learn.
edit - some people are thinking there are only 4 tiles that transition perfectly, some other people are thinking there are no transitions at all, so for clarty : the large swatch DOES contain unique, fluid transitions (albiet hastily done) -- only the 4 base tiles are shown above. They do tile with themselves, but require some help to flow into each other.
