The war against super-sized burgers and palatial McMansions has a new front, and it is defended by more than toy soldiers. Swarm Gallery, known for its brainy, ambitious exhibitions, has enlisted more than 75 artists across the country to create works of Lilliputian scale: eight-inches square, to be exact. Including pieces by local artists Kevin E. Taylor, Christine Wong Yap, and Paul Madonna, The Little Show encourages an interactive intimacy with each tiny objet d'art and validates scaled-back economy in the face of economies of scale.
