“Blue Rain” installation by Michael Brown at London School of Economics (London, England)

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.
