When you are given an assignment to demonstrate the awesome special effects possible on paper, you need subject matter worthy of such dazzling printing feats. Superheroes. Pirates. Bigfoot. Weird larger-than-life creatures. Spies. It didn’t take long to figure out where to find all of them in one place – at 826 National, a nonprofit network of tutoring, writing and publishing centers for kids, ages 6 to 18. The 826 centers are “disguised” as retail stores, selling gear for “real” working pirates, superheroes, time travelers, bigfoot researchers, robots and so on.
