How should art depict the relationship between man and God? How can art best express eternal values? Can you and should you portray the face of Christ? For over 1,000 years these were some of the questions which taxed the minds of the greatest artists of the early West. In this three-part series, art historian Andrew Graham-Dixon sets out to unravel the mysteries of art from the pre-perspective era". In the first episode, Andrew traces the beginnings of Christian art in the declining Roman Empire, Egypt and medieval France, and reveals the ideas which lay behind the transition

Welcome to an extreme landscape of rock, ice and snow. We tour the mightiest mountain ranges, starting with the birth of a mountain at one of the lowest places on Earth and ending at the summit of Everest. Find out how some of the most secretive animals rise to the challenge of mountain life. Share one of Earth's rarest phenomena, a lava lake that has been erupting for over 100 years. The same forces built the Simian Mountains where we find troops of gelada baboons nearly a thousand strong. In the Rockies, grizzlies build winter dens inside avalanche-prone slopes and climb the peaks to devour abundant summer moths. In another world first, the programme brings us astounding images of a snow leopard hunting on the Pakistan peaks.

P.U.L.S.E is a Pink Floyd concert video taken from the 20 October 1994 concert at Earls Court, London. PULSE records the great psychedelic band Pink Floyd rocking out like only they can. Renowned for their hallucinatory special effects and lighting schemes, Pink Floyd goes all out at this spectacular (and very long) concert. Twenty-one of their classics are performed, including classic rock radio staples 'Dark Side of The Moon' and 'Wish You were Here". There was considerable delay in the release of the video edition of Pulse. The cause of the delays was reputed to be the continued modifications and additions to produce a high-quality release. The previous planned release date of 22 September 2005 for the two-disc DVD set was changed to 10 July 2006 for the UK and Europe, and 11 July 2006 everywhere else.

Open your eyes to the bizarre, ferocious and surprisingly beautiful world of the invertebrates, a ground-breaking exploration into a spectacular miniature universe never normally seen but teeming all around us. In the first episode, the story of the land-living invertebrates. Discover the private life of Europe's dramatic leopard slug, a common garden resident with a truly bizarre end to its marathon mating ritual; watches the courtship ballet of tiny springtails on the underside of a leaf; sees swarms of bright red South African millipedes find partners, and in the caves of Venezuela meets the giant bat-eating centipede.

The world of invertebrates exists in a web of relationships with plants and other animals. Unique footage of the world's smallest insect (a fairy wasp only quarter of a millimetre long) shows it flying underwater to find the eggs of water beetles in which to lay its own brood. Some ants 'farm' the trees that give them shelter, creating areas known as 'Devil's gardens'. To make sure these grow without competition, they kill off other seedlings in the surrounding vegetation. The blister beetle's larvae huddle together on the end of a piece of grass and mimic a female bee. When a male bee tries to mate with the 'female', the larvae grab on to his belly. Confused, he flies away and searches for a real female. When he eventually finds her and mates with her, the beetle larvae hurriedly swap from his front on to her back, and hence get carried back to her nest where they eat her pollen supplies.
