Nestled into the corner of the library façade are more than 23,000 blue Light Emitting Diodes (LEDs). To the casual observer, a shimmering cascade of light appears to flow down the wall but it becomes quickly evident that what one sees are actually words flowing through each other at different rates. By tracking one line of text, the observer will discover that they are looking at research being carried out within the library, bringing what is going on inside the library outside.
This is installed in the atrium of the Wellcome Trust headquarters in London and public tours are available on the last Friday of each month at 2pm.
The swan is life-size and is controlled by three separate clockwork mechanisms. The Silver Swan rests on a stream made of twisted glass rods interspersed with silver fish. When the mechanism is wound up, the glass rods rotate, the music begins, and the Swan twists its head to the left and right and appears to preen its back. It then appears to sight a fish in the water below and bends down to catch it, which it then swallows as the music stops and it resumes its upright position.
You can see the Swan in action every afternoon at 2.00. This performance lasts approximately 40 seconds.
The Museum is in the picturesque market town of Barnard Castle, County Durham situated in the heart of the Pennines in North East England.
