Sorry for the lack of reply about my G.K. Chesterton wallpaper. Life got really screwy and I hadn't been back to DA until just recently. I actually forgot I made that one, and I lost it in a hard drive crash, so yay me!
You were right - it's simple - but it took LOTS of tracing in illustrator to get that silhouette! Probably a piece of cake with the software we have now.
