This is very cool -- the Smithsonian American Art Museum is planning a proper exhibit of video game art; judging from the website, it will at the least include some beautiful concept paintings from more recent games, and plans to cover five generations of video game technology and visuals.
Better yet, they're soliciting input from gamers from February 14 through April 17, 2011 -- you can vote for 80 games out of a pool of 240 worthy nominees. The voting site requires registration, to minimize stuffing of the ballet boxes, so let's all be honest and keep this dignified.
I wish there was more interactivity planned -- the exhibit will feature only five significant games as live, playable examples -- because in my opinion that's where the true art of gaming lies. But this is a conventional art museum, and a well-respected one, so the exhibit's focus on the visual aesthetics of gaming is completely appropriate.
Visit the Smithsonian American Art Museum's Exhibitions: The Art of Video Games site to learn more about the exhibit, and visit the voting site to express your opinion.
