The bridge  of a ship is the room or platform from which the ship can be commanded. When a ship is underway the bridge is manned by an OOW (officer of the watch) aided usually by an AB (able seaman) acting as lookout. During critical maneuvers the captain will be on the bridge supported, perhaps, by an OOW as an extra set of hands, an AB on the wheel and sometimes a pilot if required.

The "Bridge" is an evolution of continuing excellent CHAOS at noisebridge, and has become the corner of Spacebridge, Fort & HiR. The "Bridge" is intended to be an experimental platform for exploring the future of hack space. The "Bridge" quickly evolved over a week starting with 30c3 as we ended the year known as 2013. Since that time it has continued to evolve into a ambitious and controversial point of intrigue, speculation and CHAOS.
