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 Ferrolic after 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 rocket fuel.

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.
