Most of the textures were freely available on the net. Some of them I did myself. If you do a search for free scifi textures or free video game textures you'll come up with a bunch. The photoshop files are huge (234mb) and meant to be printed at 300dpi so they won't fit here. I've attached a picture of the whole set so that you can see how to assemble. I'm not sure how long I'll leave the source files up so grab it before it disappears. Here's the link to the files:
