This was my senior project where we got an inspiration from the Osaka City Station waterfall, which water droplets are displayed in visual forms. The prototype is in a size of 32X8 pixels. Using 32 solenoid valves and the design is constructed to be 3 meters high.
Once compiled the interface should look like below. ![alt tag] (http://raynecarnes.files.wordpress.com/2014/02/screen-shot-2014-02-24-at-6-47-30-pm.png?w=665)
