Actual art on @ a college?

The Corpus Clock is a large sculptural clock on the outside of the Taylor Library at Corpus Christi College, Cambridge. It was conceived and funded by John C. Taylor, an old member of the college.
It was officially unveiled to the public on September 19, 2008 by Cambridge physicist Stephen Hawking

The clock’s face is a rippling 24-karat gold-plated stainless steel disc, about 1.5 metres in diameter. It has no hands or numbers, but displays the time by opening individual slits in the clock face backlit with blue LEDs; these slits are arranged in three concentric rings displaying hours, minutes, and seconds. The lights dart rapidly around the clock, pausing at the correct positions allowing the time to be read as on a normal analog clock.
The dominating visual feature of the clock is a sculpture of a grim-looking, devouring, metal insect similar to a grasshopper or locust. The sculpture is actually the clock’s escapement (see below). Taylor calls this beast the Chronophage (literally ‘time eater’, from the Greek χρόνος [chronos] time, and φαγέω [phageo] to eat). It moves its mouth, appearing to ‘eat up’ the seconds as they pass, and occasionally it ‘blinks’ in seeming satisfaction. The creature’s constant motion produces an eerie grinding sound that suits its task. The hour is tolled by the sound of a chain clanking into a small wooden coffin hidden in the back of the clock.
The clock is entirely accurate only once every five minutes. The rest of the time, the pendulum may seem to catch or stop, and the lights may lag or, then, race to get ahead. According to Taylor, this erratic motion reflects life’s “irregularity”.
Conceived as a work of public art, the Chronophage reminds viewers in a dramatic way of the inevitable passing of time. Taylor deliberately designed it to be “terrifying”: ‘Basically I view time as not on your side. He’ll eat up every minute of your life, and as soon as one has gone he’s salivating for the next.” Others have described it as “hypnotically beautiful and deeply disturbing”.
[edit]Mechanics of the clock

The Corpus Clock is a product of traditional mechanical clockmaking. It features the world’s largest grasshopper escapement, a low-friction mechanism for converting pendulum motion into rotational motion. The grasshopper escapement was an invention of eighteenth-century clockmaker John Harrison, and Taylor intended the Corpus Clock to be an homage to Harrison’s work. Since “no one knows how a grasshopper escapement works”, Taylor “decided to turn the clock inside out”[6] so that the escapement, and the escape wheel it turns, would be his clock’s defining feature.
The Corpus Clock’s clockwork is entirely mechanically controlled, without any computer programming, and electricity is used only to power an electric motor, which winds up the mechanism, and to power the blue LEDs that shine behind the slits in the clock’s face. The clock has many unexpected and innovative features; for example, the pendulum briefly stops at apparently irregular intervals, and the Chronophage sculpture moves its mouth and blinks its eyes. Taylor explains it as follows:
The gold eyelids travel across the eye and disappear again in an instant; if you are not watching carefully you will not even notice. . . . Sometimes you will even see two blinks in quick succession. The Blink is performed by a hidden spring drive, controlled in the best tradition of seventeenth century clockmakers of London. The spring is coiled up inside a housing that can be seen mounted on the large gearwheel visibly protruding from the bottom of the mechanism. As the huge pendulum below the Clock rocks the Chronophage as he steps round the great escapewheel, each backward and forward movement is used by sprag clutches to wind up the drive spring. A position step prevents the spring from being overwound yet allows the spring to be ready at an instant to drive the Blink. The mechanism is released by a countwheel with semi random spacing so the Blink takes place at any position in the to- and fro- motion of the pendulum. A further countwheel mechanism chooses a single or a double blink whilst the air damper at the top of the gear train slows the action to a realistic pace.
The Corpus Clock is expected to be able to run accurately for at least two hundred years.
[edit]Funding and realisation

Taylor invested five years and £1 million in the Corpus Clock project, and two hundred people, including engineers, sculptors, scientists, jewellers, and calligraphers, were involved. The clockwork incorporates six new patented inventions, and “the rippling gold-plated dial was made by exploding a thin sheet of stainless steel onto a mould underwater . . . [at] a secret military research institute in Holland.” Stewart Huxley was the design engineer. Sculptor Matthew Sanderson modelled the Chronophage.

    That’s awesome. Thanks for the link to the vid.

    I like this. It’s nice to see new art that isn’t just random and meaningless.
