The current theme at Collage Obsession is "Steampunk and Beyond." I've never been a fan of steampunk; in fact, I find some of it kind of scary. However, Order of the Opus Gluei has a theme of "Go Where You Haven't Gone Before" running. I think someone was trying to tell me something.
I stayed away from the scary side. Mostly scrapbook paper plus an old mechanics book I have which is full of numbers, diagrams, and other usually mundane info. Here it looks pretty good.
