The Smithsonian Institute's Cooper Hewitt design museum got a recent overhaul, and at its core is something app developers are likely pretty familiar with -- an application program interface. We know what you're thinking, "What does a museum need an API for, anyway?" Well, it turns out that this basically makes cataloging its massive inventory and making it linkable on the web a reality. The interconnectedness of the inventory means one aspect of the museum can draw upon another in ways that are visitor-facing, as well. For example, The Atlantic notes that there's a so-called "immersion room" that projects patterns from the outfit's wallpaper archives onto the walls. Sounds pretty neat if you ask us.
