Millions of tiny pieces of liquid crystal are most likely switching on the computer screen you are looking at right now. It’s normal state is opaque, but when a little electricity is added, it goes transparent. In the past decade or so, manufacturers have begun to use it in larger pieces on windows to provide privacy and protection from the sun. IDEO even used it for the doors of changing rooms. We saw the possibilities to use this material in a unique way. Through the use of custom software and circuitry, we were able to simulate the look and behavior of weather patterns from around the world.

We wanted the eCLOUD to behave as if it were dropped into a city around the world and effected by it's specific weather conditions. If it were windy in Rio de Janeiro, the animations in the installation would behave in a way the evoked the wind and direction it is going in that city. In a few seconds, the cloud is metaphorically moved to another city, lets say Sao Paulo, and it were raining there, then our cloud would look like it is raining.

We show this on a large dynamic display that is running custom software which pulls data from The National Oceanic and Atmospheric Administration (NOAA) about international weather conditions. This data is used to create a simulation representing weather from any of the international locations. The simulation is visualized within the cloud sculpture as well as on the dynamic display sign in the terminal. The dynamic display also shows the current location being visualized and the NOAA data driving each animation.

The software, was written in Java and was built upon Processing (processing.org). Each panel’s position is logged in the software and is distance checked against the particle simulator which simulates clouds, rain, ice, storms, etc..

The eCloud has 100 custom designed circuit boards that control the liquid crystal pixels. As information is sent from the master computer, it goes to the circuit boards, then they tell each pixel wether to turn on of off. Each board can have up to 30 pixels attached to it.
