My friend Michael Douma developed an app that shows how the genre can demystify complex concepts and make them simple and approachable.
He developed the original time.gov site (the official clock of the United States) and took the idea forward, educating the world about how time zones and time changing works through a web exhibit.
The culmination of the effort is an app that not only packages the web site but allows for a new level of interaction to educate and illustrate the reasons for the confusing and frustrating ritual of changing of the clocks.
By adapting web content to interactive app content, the concept leaps off the screen. You can learn about the rationale of clock changes, get the historic perspective, the international variance, be alerted to the shifts, alert others and, of course, find out when the change happens no matter where you (or your friends) are.

 I was modestly involved in the concepting.
