No secret. Most of the textures in the backgrounds are hand painted. For the bricks, I used a high resolution photo, stitched it together to make it seemless, and then color matched it to the wall that I had thrown on a little color. Since Parson is in the real world, I wanted it to look as real as possible without going totally photo-realistic. I guess you could call it cheating, but I still had to do the work.
