I guess the C was the simplest solution, and works.
It took me a while to think that up, but once I thought of it, I thought it was excellent for what had to be done.
in fact I think it works so well that it might be better saved for something more significant.
We can always change it later if we think it's better reserved for something else. I'll leave it for now. Alternatively, you can use it to play as a different tile.
Edit: I guess there aren't any more comments, so I'm going to put this up on the Public Downloads.
