Perhaps the greatest biblical riddle ever. The Ark of the Covenant was terrifying beyond belief - consuming those who sought to look upon it in fire or disfiguring them with tumours and leprosy. Then it simply vanished. Join National Geographic on an epic scholarly journey in search of the truth behind one of the most coveted artefacts of the Bible.

Its one of the most coveted artifacts of the Bible: a gold-encrusted chest containing the Ten Commandments. Can modern scholarship explain the awful powers of the Ark of the Covenant and tell us how it vanished and where it is today* In Hunt for the Ark, we ask whether this golden casket that contained the Ten Commandments really existed, and if so, whether there is any logical explanation for its mysterious disappearance. Was it really spirited away from Solomon’s Temple by the Knights Templar?

Across the Himalayas are stories of the yeti, or abominable snowman. Half man, half ape, the yeti is said to roam only the most remote peaks, where people rarely venture. Now, veteran explorer and climber Gerry Moffatt sets out to find proof in a hunt that will test his stamina.

Seven years ago, on his third trip to the Black Sea, Dr. Robert Ballard discovered a miraculously well-preserved Byzantine shipwreck, but his team could only take pictures. Now, Ballard returns with state-of-the-art technology and a revolutionary $1.5 million robot known as Hercules to excavate two shipwrecks for the first time ever, including one of the most pristine ancient vessels ever found. Ballard and his team have only two weeks, so they must work in perfect precision on their hunt for the Ghost Ships of the Black Sea.

This DVD is the first of a two part series that introduces Proceduralism within 3dsmax. Chris guides you through the concepts of a nodal architecture by looking at practical examples in 3dsmax , Maya and Houdini , and goes on to show how it is accessed in Max via its Stack interface. He then continues onwards to show how large and small elements can be instanced, and outlines important issues such as stack evaluation and topological dependency.

Ever since the earliest missionaries and explorers returned from Africa, stories have been told of strange water-dwelling monsters living in the Congo Basin. The native Pygmy tribes speak of the Mokele-mbembe, an animal with a long, thin neck and a body the size of an elephant that seems to resemble a sauropod dinosaur. Could there be a population of dinosaurs living in the remote jungle?
