Look up, because this is a clock that refuses to behave like one. You are in the Shiodome district of Minato Ward in Tokyo, beside the Nittele Tower, the headquarters of Nippon Television. Hanging outside the second story of the tower is the Ni-Tele Really Big Clock, known in Japanese as Nittere Odokei. This is a clock and a sculpture at once, designed by Hayao Miyazaki, the animator and co-founder of Studio Ghibli. Most of the day it looks like a vast, intricate piece of metalwork. Then, a few times a day, it wakes up, spinning, whirring and clanking through a short performance. Over the next few minutes we will look at who dreamed it up, what it is made of, and how to catch it in action. The tale here is about the clock itself, a free public spectacle in the middle of a business district.
