I didn't realize Uru could handle textures that repeated in a pattern other than a rectangular one. I'll have to learn how to create repeating tiles of other kinds now!
Here's another texture I put together in light of Pavitra's suggestions--not an edit of the first one but an entirely new texture. I like this one a lot better than the last, but it could probably still be improved. One thing I'm not sure about: I used slightly imperfect hexagons and intentionally made it so the symbols don't all line up perfectly. This was all done on purpose to try to give it more of a "hand-made" feel. If people don't like it, it would be fairly easy to redo this in a way that everything would line up perfectly. Let me know what you guys think:

EDIT: I forgot to mention, this texture is not actually usable yet--when doing the engraving I took a shortcut in order to finish it faster, and as a result the engraving lines will show a "seam" in places. I will of course fix this if we end up deciding we want to use this texture (along with making some other improvements).
EDIT2: I realized I should probably explain what I'm going for here. With both of these textures, I was trying to incorporate the GoW symbol in a subtle but visible way. The idea is that it shouldn't jump right out at the players and say "Look! I'm the Writer symbol and I'm all over the place!", but should still be recognizable to anyone paying close attention--so that a player might suddenly say, "Oh! I just realized that the floor pattern has the Writer symbol repeating in it!" With the first I failed--the symbol is nearly invisible when viewed at an angle. The second one, when Bryce-tested, seems to give the proper effect (at least to me)
