Looking for a Damascus Steel Tileable Pattern

[Coriolis]

After some trial and error with the automated distort filters, I discovered Iwarp. The swirl tools were particularly useful., I found I liked a randomized approach, so I just held the mouse button down and squiggled all over the place. The result isn't tileable, but it's easy enough to custom do for any size texture in a minute or two.

So yeah, here's the step by step (this is for GIMP, but I imagine PS has some similar feature):
1. Get a steel texture, preferably one that isn't too clean.
2. Dial up the contrast by 30 or so with the Brightness/contrast.
3. Go to Filter > Distort > Iwarp.
4. Select Swirl (either direction). The default is ok, but I also checked the box for "Adaptive Supersample", as it seemed to produce a slightly better result.
5. Take two long passes, holding the mouse button down. Work your cursor over the whole area like a zamboni, until you have swirled every pixel on the texture. Hit OK, and inspect your work.
6. For a more randomized appearance (which I prefer), take another pass, but this time just make a scribbling, shaking motion with the mouse, with no pattern or structure to where you swirl.
7. GIMP left the bottom and right edges un-swirled for reasons that I could not discover. If this happens, use the flip tool to flip the layer horizontally and vertically. Then Filter > re-show Iwarp, and swirl the previously-unaffected areas.
8. go to Color > Brightness/Contrast and adjust until you're satisfied.

I was a little worried that I might over-swirl the texture, but that doesn't seem to be a problem.
