When Piet Hein Eek started his Tube series for LEFF amsterdam, his starting point for the Tube Clock’s dial was an extrusion ring. Extrusion molding is a design technique that involves forcing materials through a mold, the extrusion profile is what gives the material its shape. Piet Hein devised a ring like that for the design of the clock face. A good idea can be surprisingly simple – often the simplest solutions have not yet been invented. This clock could have been designed a century ago, it’s actually a textbook example of LEFF amsterdam's philosophy: the idea of keeping things normal and down-to-earth, but still extraordinary. **Check out the matching LEFF amsterdam Tube Audio Bluetooth Speakers!
