Open Data Day [new time and venue]

Hacking and making things that use or generate open public data of any kind as part of the international Open Data Day Hackathon http://opendataday.org/. We can go local, from open source air quality sensors for Cambridge to visualisations using local government open data, or global with a whole range of hardware and software projects to choose from. There are already 86 events happening all over the world (http://opendataday.org/map/) and online connections are encouraged so we can wave goodbye to Japan in the morning and pass the baton onto West Coast US before heading to the pub.
