Creativity, Inc: Dave Eggers of McSweeney's is a proprietor. A shopkeeper. Perhaps even a franchise magnate! It was his keen perception of unmet needs in niche markets that led to the opening of a growing array of supply houses across the country. Among them: The Pirate Store, for the well-outfitted swashbuckler; The Boring Store, a subtle, unassuming purveyor of goods for secret agents; the Superhero Supply Store, in Brooklyn, carrying all the eyewear and accessories today's world-savers require; and Greenwood Space Travel Supply, where customers are reminded of the space-travel axiom "A lack of preparation is a prescription for mishaps." If these sound like curious business ventures for a celebrated author, there's a reason: the storefronts, though real, are just that - fronts. They're the streetside faces (and fundraising arms) of the nonprofit 826National, a family of learning centers for kids ages 6-18. The 826 'stores' provide free field trips, creatively themed writing workshops, publishing, and one-on-one instruction. Supported by an impressive field of cultural types (including Ira Glass, Sarah Vowell, Sherman Alexie, and others), the program is growing. Coming soon: Michigan 826 will open Monster Union Local 826, and 826LA will open the Echo Park Time Travel Mart.
