I fiddled with a free texture, similar to the pattern from the OP, but with the grain in the “correct” direction and hue adjusted to get better contrast with both stone colors) and came up something like this:
variation: slightly desaturated, blurred, and luminace to match more closely the default ogs board. I find this a less drastic change from the default, which I think is good for keeping a focus on the stones.
@tozgrec, do you happen to know where these wood texture images came from? Or are you the author?
Are they available under some sort of open license (like Creative Commons)? I would like to use and redistribute them as part of an open-source software project (see BesoGo), but I want make sure that I can obtain the appropriate permissions to do so.
However, I’m sorry for my laziness/ignorance, but I’m having trouble adjusting the external padding and sizing of the tiles so it fits OGS’ grid, and there’s also the problem of having coordinate on OGS’ grid. If I have the patience, at some point I’ll create the necessary variations, in the meantime, I hope someone else has the kindness of creating them before me — and I hope they also come up with a systematic approach to this problem.
In the code below, the last part is what’s important if you’re trying to modify the words, labels and size. For the size, you just need to change the 18's.
You can use Overleaf if you’re having trouble instaling LaTeX.
