We built a clock that displays a series of arcs representing the time by rotating very fast a single LED strip and giving the illusion that the clock is made by continuous arcs of light. <br>The LEDs are turned on and off with appropriate timing, so thanks to the principle of persistence of vision, the eye is under the impression that what it&apos;s seeing is not a strip of LEDs rotating, but a continuous beam. <br>This display was made for the 30th anniversary of Quasar Design University, Rome. <br><br>The project was created in collaboration with Sara di Bartolomeo (<a target="_blank" rel="noopener noreferrer" href="http://picorana.github.io">picorana.github.io</a>) as the artist collective &quot;We are teapots&quot;
