Even though the Spire Clock may not look like a time teller, its unique design does actually tell viewers the time of day.
The reason for the Spire Clock's unconventional form is because the design was inspired by a Japanese fan. The longer blade represents the minute hand while the shorter one represents the hour hand. Time is told based on the movements of the folding fan, but more specifically, on the concept of mass and void. The hour is "represented by a mass contained within the longest and the shortest blades," according to Red Dot. As each hour progresses, the mass will change its form and by the end of the hour "the blades turn quickly to transform the void that represents the next hour into mass."
Still a little confused as to how the Spire Clock works? Watching the video may clear things up.
