In the Grand Prix of the Pacific, teams race outrigger canoes across the 40 miles of surf, dangerous currents and huge waves that separate two Hawaiian islands.

It was designed for the King of Spain to sit on during the Barcelona World's Fair in 1929. When the designer, Mies Van Der Rohe, found a casual passerby sitting on one, he ordered him towards the more appropriate benches which he'd designed outside for people like him.

The elitist image has never worn off. Expensive, austere, it's as much a work of architecture in its way as Mies's influential if stark buildings. It's a chair to admire rather than settle back in. It's still very much in production, an icon with its roots in the Bauhaus and the heroic age of modern design.

Narrated by Jancis Robinson
with Penny Sparke, Richard Seymour, Dick Powell and Arthur Drexler

The information-hungry world of the 21st century will be fed not by electrical signals, but by pulses of invisible laser light flying along fibres of glass.

What is the revolution in communications that has ousted electricity in favour of light?

With crashing motorbikes, stretching trains and a semiconductor laser the size of a department store, Horizon investigates the mysterious world of light technology and, at the frontiers, finds plans for computers that will process information with light.

What all this might mean for people 25 years from now is seen in the touching tale of Alan and Sarah.
