A water clock (or clepsydra) is an instrument where time is measured by regulating a flow of liquid. The oldest water clocks simply consisted of a pierced bowl placed in a larger pot filled with water (see left image, Persian artefact from 400 BC). These existed back in the 16th century BC. The passage of time was observed by counting how many times the bowl overflowed and its […]
The MONIAC or Phillips machine is a hydromechanical analog computer built to teach basic economical principles using colored water flowing in transparent pipes. The machine was built in 1951 after electrical-engineer-turned-economist William Phillips and his economist colleague Walter Newlyn realized that flows were used as a metaphor to teach economics, but have never been made physical. Phillips is also known for his eponymous curves. Several MONIACs were built, and a working one is permanently displayed at the Economics Department of Cambridge University.

As a response to devastating floods of the Mississippi river in the early 1900s, the US Army Corps of Engineers built a large-scale hydraulic model of the entire river system. The model, 2.5 times the size of Disneyland, allowed them to design better flood control infrastructures and to eventually save millions of dollars. In 1973, the physical model ceased to be used and was replaced by computer models. Nevertheless, mathematical equations […]
Chrisantha Fernando and Sampsa Sojakka from the University of Sussex published a paper where they demonstrate that a bucket of water can carry out complex, parallel computations, and can even do simple speech recognition. Their setup called "liquid brain" consists in a transparent water tank suspended over an overhead projector and four LEGO motors. Input values are sent to the motors which vibrate the water. A camera […]

Pulse Drip Interactive installation originally developed for Urdaibai Art 2012 in which the public can water the lawn at the Torre de Madariaga using a water hose with a heart rate sensor built-in. To participate, visitors take the hose wherever they want to water: by putting their index finger on a tiny sensor on the spray head, his or her pulse is […]
“Water Works” is a 3D data visualization and mapping of the water infrastructure of San Francisco. These consist of three large-scale 3D-printed sculptures, each generated by custom C++ code. The concept behind the project is to make visible a small portion of an invisible network of pipes underneath our feet. The three physical data visualizations are: "San Francisco Cisterns", “Imaginary Drinking Hydrants” and "Sewer Works". "Sewer Works" uses […]
This data sculpture made by three design students at the datafossil #3 workshop depicts the destruction of Australian coral reef since 1985 (in orange) together with the rise of ocean temperature (in gray). The Great Barrier Reef has been losing more and more of its area since the last 27 years. One of the biggest cause is coral bleaching due to global warming and more exactly to the rise of […]
