This is by far the most awesome combination of science and design I’ve seen: a clock created by Zelf Koelman that displays time with liquid. It’s called Ferrolicafter the ferrofluid which can display recognizable shapes in response to magnets embedded inside the clock’s aluminum frame.
A ferrofluid (put together of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field. It was invented in 1963 by NASA’s Steve Papell as a liquid
Ferrolic is controlled by an intelligent internal system that is
accessible trough a web-browser. The inventor wrote in this way users can assign “the
creatures” to display time, text, shapes and transitions. The clocks are more of a prototype so far, the first ones were available at a price of about $8,000 each.
