Well, this was an experiment in making an image and trying to make it look like it was on the screen of a really crappy television. It took hours of experimenting to find something I liked, since simple lines set to overlay just didn't work for me. I finally settled on merging a number of different tips I've seen or techniques I've done and got a result I'm satisfied with. It took maybe... four hours to finally settle on a method for the television-y look (I admit, I got a tad OCD about that)... and after I settled on that I got started building the wall itself. I spent about three days just fussing with it before getting it to this point.

The script brush I used is by scully7491 at deviantArt.
