Yesterday marked the tech industry's advocacy action, The Day We Fight Back.

On a cool morning a group of hackers slowly filter into a downtown Philadelphia storefront. The whiteboard wall quickly fills up, as a few work on finding an accurate way to track the progress of a single chosen bus line.

A few keystrokes and another starts tracking the positions of trains, while across the the room, transportation information flickers across a screen, controlled simply by a pair of hands moving through the air.
