My project partner Stacy Bond (that’s Bond, Stacy Bond) and I built and presented our iPad app at Hack/Hackers Unite this weekend. Our project? “Ephemera” an overlay of the map of SF with local trivia/history.
The app locates you, and shows all of the annotations for local treasures around you. You can also click over to look at the treasures, instead of clicking on each ephemeron.* Using MapKit framework. We load it up with all of the trivia for SF (currently). Future developments may include a time-slider to view a location over time. Code is available at: http://code.google.com/p/secretcity/
Historical sources for the ephemera: SF Historical Society.
* Points for knowing the singular of ephemera!!
