Siphonophora by Rob Davis and Usman Haque

It's not exactly Open_Sailing, but it looks very similar! This is a cool project looking at making aquatic devices that react to their surroundings. They should be living in Gunpowder park right now.

The Siphonophiora project uses small reactive devices situated in one of Gunpowder Parks lakes to record and observe environmental data. Borrowing its name from a class of marine invertebrates, Siphonophora is an interactive research project by Rob Davis and Usman Haque. The small reactive devices will track light, temperature, pH levels and other pond life activity, feeding this information live onto pachcube.com, a website which collects environmental data worldwide and which will compare this information with other natrual sites all over the world.
