Serendipitor is an alternative navigation app for the iPhone that helps you find something by looking for something else. The app combines directions generated by a routing service (in this case, the Google Maps API) with instructions for action and movement inspired by Fluxus, Vito Acconci, and Yoko Ono, among others.

The Accidental News Explorer is a new type of news app that celebrates chance encounters and serendipity. Start by searching for a subject. Once you've browsed the suggested articles taken from hundreds of news sources, tap the “related topics” button to discover connected topics, which in turn lead to more articles. Each article leads to new things; the more curious you are, the longer your journey will be. What will you discover?
