In Dublin, Ireland, rainfall is frequent and unpredictable. Often individuals carry umbrellas with them in case they are caught in a downpour. It is common to witness during a sudden and unexpected flash of rain, a sea of umbrellas in the crowded streets sweeping open as raindrops first hit the ground. This collective, yet isolated act of opening an umbrella creates a network of individuals who are connected through similarity of action, and intent. The manifestation of open umbrellas on the street could be tied to a temporary network which is activated through routers and nodes attached to the umbrella, which operate only while it rains. While the coincidence of need exists, the network operates. When the necessity of action and intent ceases, it disappears. We believe these transitory networks can add surprise and beauty to our currently fixed communication channels.
