Working on it. In the meantime, you mind explaining your process a bit?
Not at all, although it is very hard to explain with text alone.
First I started with a base metal color, which I also made from scratch with a solid color with added noise + the blur, dodge and burn tools. That's another story. Anyway, I filled a 2048 x 2048 blank canvas with the base metal texture, and then I set out to make the shapes of the circles and lines.
To make the circles I Shift + dragged to make a circle, and filled it black. Then, in Blending options I checked stroke and colored the stroke another color, which expanded the borders of the circle a little.
Then I rasterized the layer and selected the colored border with the magic wand, and deleted the inside of the circle, so I effectively just had the border around the circle. Then I simply duplicated the circle and placed it accordingly with Raven's texture, and connected them with the black bars. After that I merged all of the circles and bars together, and I beveled and embossed them inward to give them depth. Then I lowered the opacity of all of the black circles and bars a little, and then added the rounded rectangle things with Photoshop's rounded rectangle tool. I had to edit the radius of the rounded rectangle though so it was fat enough, like raven's texture.
Finally, I put a metal texture I had found on CGTextures over it and set it as overlay in the layers dropdown box, which gave it all of the metallic details without having to laboriously paint them all in (not to mention I suck at painting).
I should write a tutorial when I have the time. Making textures is not very hard, but it's very time consuming if you want the final product to actually look good. That door texture took about an hour to make, although since the floor I made was simpler that took me like 20 minutes.
