I flipped the Ox image in Horizons, because it looked too much like the Knight image in the way you had drawn it. I think piece images should be quite different even when looked at in low resolution. If I would flip the Ox here, it would become too similar to Index. Of course I could flip them both. But I don't think it is a problem that the Ox in Horizons and Stone Garden Chess look the same, although they move differently. They are also called the same, and this is actually more confusing than that the image is the same. People would not easily remember in which direction the Ox looked in another game, They might not even know the other game.
OK, I fixed that now.
