It's the most extraordinary feat of engineering in history, and one of the most iconic man-made structures on the planet - the Great Wall of China, stretching thousands of miles across barren deserts and treacherous mountains before finally plunging into the sea. But why did the Chinese go to such staggering lengths to build it, and what are the secrets that have enabled it to survive for over 2,000 years? Now, ground breaking science is re-writing its complex history and de-coding its mysteries to reveal that there is much more to the Great Wall than just bricks and mortar. Cutting edge chemistry reveals that the secret to the Great Wall's remarkable strength is a simple ingredient found in every kitchen, and a new survey also determines that its length is truly amazing, as we finally solve the enigma at the heart of the world's greatest mega-structure.

This is a thoughtful and mature documentary that considers whether online rage has real-world consequences. Baddiel has experienced antisemitic abuse on Twitter, where he has 785,000 followers. He has had brushes with what is called “cancel culture” and “callout culture”, when users have criticised his use of blackface on TV in the 1990s, for which he has apologised. He is also a self-confessed social media addict – by which he really means Twitter, his primary focus here – and self-aware enough to admit that while he feels he needs it to promote his work, he also understands that he has a psychological need for an audience, and by extension, for audience approval.

Flowers, Animals, Grass, Sky, Loved ones, Like, Follow, Comment. View the forgotten and ruined memories that have been tainted by earworms, bad comedy and the far-right pipeline. Gaze upon the endless landscape, or gaze upon the endless thirst traps.

A film about fireworks, the people who make them and the cultures behind them across the globe.

One of the first works by María Cañas, an excessive metadiscursive exercise on the “pig character” of current information and archive culture.

Explores the history, technology, people, stories and industry influence of this lesser-known personal computer. The film profiles important individuals involved in the creation of the computer, plus its life after cancellation, both as an entry-level Macintosh compatible and as a collectible. The work of Douglas Engelbart and his team, plus advances from the Xerox Palo Alto Research Center (PARC) with their Alto and Star workstations were the initial innovators of the Graphical User Interface (GUI), but the Apple Lisa stands as the clear foundation for what we all use today - Macintosh - Windows - iOS - Android.

Film sponsored by Western Electric (AT&T's equipment manufacturing division), the builder of the United States Air Force's White Alice Communications System in Alaska. Introduces the people and geography of the new state as well as the Western Electric radio-relay system, which links far-flung military sites, alert stations, and missile-warning facilities. Ralph Caplan praised the film's "intrinsically dramatic and highly photogenic" portrayal of communications equipment.

The story of computers: from electronic tape and punched cards, to austere-looking robots.

A documentary about the past, present and potential future of the Digital Compact Cassette. Very few people know the true story about, the Digital Compact Cassette or DCC. Was DCC's audio compression the grandfather of all compressed audio formats today? Why did it have such a short life? Why didn't it become popular in more countries? The early termination of the format in 1996, leading to the rejuvenation in 2014 by Techmoan and later the DCCmuseum in countries that rejected the format before. Nearly 2 years of research allowed us to finally get the truth about DCC on camera, presenting DCC enthusiasts the past, present, and potential future of the format we love. This documentary is about the format, the creators, the decision makers, the musicians, the collectors, the geeks, and the audiophiles behind DCC.
