Your eyes aren’t playing tricks, nor is this computer-generated imagery, just Zelf Koelman’s latest project: Ferrolic. This alarm clock, which looks like a Rorschach test, relies on magnetic ferrofluids – a liquid that becomes strongly magnetized in the presence of a magnetic field – to display the time. “A few years ago I fell in love with the magical characteristics of a little black ‘blob’ in a bottle. One could manipulate the position and shape of a floating drop of Ferro Fluid with a magnet. The dynamics and shape of this liquid body was much like a living entity. I decided to allow this entity to live its own life and have a function.
A year of research and engineering eventually resulted in Ferrolic,” said Koelman. Tired of just seeing the time? You can use a web app to display texts, images and more.
