Today the Smithsonian American Art Museum in Washington, DC opened an exhibition called "The Art of Video Games."
(Video link) The show contains original art and interviews with designers, developers, writers, programmers, and scholars. Curated by Chris Mellisinos, it is divided into three parts, exploring the "creative process, the mechanics that allowed things to move forward, and the evolution of form over time."
The exhibition will be on view through September 30.
There's also a book called The Art of Video Games: From Pac-Man to Mass Effect
