The covers of most university catalogs typically show photos of the campus or students lounging around the quad, or just present a plain typographic title. The covers for the University of California Los Angeles (UCLA) Extension catalog are an exception to the norm. Since 1990, they have featured the works of several of the world’s best-known graphic designers, beginning with Paul Rand.
Korea’s largest retail chain, Emart, found that slumping sales at midday were casting a shadow over its revenues and came up with a clever way to attract lunch-time shoppers. At its 38 locations throughout Seoul, Emart installed three-dimensional QR codes on outdoor pillars located to catch the sun. Like a sundial, the shadows on the QR code moved as the sun changed position, and passersby were alerted that they could only read the QR code’s message between 12 noon and 1 pm. Consumers who scanned the code were directed to the Emart online store where they received $12 coupons for products that would be delivered to their homes. Thousands of consumers claimed Emart vouchers, and sales increased by 25% during the lunch hour.
