I wrote FusionTables.js to simplify building news apps on top of Google Fusion Tables. The project includes a Node.js-based proxy and a Backbone.js driver.
This is an effort to build an open-source version of the New York Times photo backpack. The project has been funded by the Knight Prototype Fund. There are two parts: a Raspberry Pi, tethered to a camera, that stores photos on Amazon S3 and a Node.js app for viewing and downloading them.
