I have a store on RedBubble! I call myself Xanaduriffic, which is an ancient word meaning "feminist, geeky merchandise with a bookish flair--also features cats."
There are tees, totes, phone and tablet skins, stickers, mugs (for coffee or wine--dual purpose!), and lots o' other crap, too. Yay! Check 'em out here: http://www.redbubble.com/people/xanaduriffic/portfolio.
