Artists and designers have explored the creative possibilities of programming since the 30-ton ENIAC was state of the art, but the last 20 years have seen an explosion in code-based forms as PCs have become cheaper and more powerful. Casey Reas and Chandler McWilliams survey digital media’s past and current practices in Form+Code in Design, Art, and Architecture. With more than 250 examples from a range of creative disciplines, it’s a wallet-friendly, slickly designed primer on the topic. $24.95; Princeton Architectural Press
