Everything I used was from a screenshot from Jumpgate Evolution...of course, I had to play with it some to make it tile worth a damn. The darker blue came from a jumpgate field, and I think turned out really well.
I was thinking about it, but Roheryn never got back to me. I was going to see if I could hitch a ride up there with him. I've got too much drama going on IRL to head up there solo.
