Dutch designer Zelf Koelman mechanized Ferrolic clock that is a self-contained clock made of electromagnetic black fluid that forms into time or any shape of form the ferrofluid is designed into suspended particles.

Ferrolic was designed from a strong fascination for the magical material Ferro Fluid. The natural dynamics of this fluid makes that this display bridges the gap between everyday digital screens and tangible reality. Because the fluid behaves in a unpredictable way, it is possible to give the bodies perceived in the Ferrolic display a strong reference to living creatures. It is this lively hood that enables Ferrolic to show a meaning-full narrative like for instance having the creatures play tag. In addition the natural flow of the material, it can be used to form recognisable shapes and characters. Ferrolic uses these both layers in paralel in order to display scenes and transitions in an poetic, almost dance like, choregraphed way.
