Big Box Watch is a Google Maps mashup showing where new retail stores are being built.

They're currently tracking Best Buy, Home Depot, IKEA, JCPenney, Kohl's, Lowe's Target, and Wal-Mart. The site draws from publicly available information and user submissions.

Personally, we're hoping for some yellow balloons (IKEA) in Brooklyn. — BEN POPKEN
