Boston Dynamics' 2010 demo of BigDog, a quadruped robot that climbs through woods, recovers from kicks, slips on ice and jogs at 5 mph. It was an early showcase of dynamic legged locomotion.

Boston Dynamics shows its Atlas humanoid robot performing a gymnastics and parkour routine, using optimization-generated motions and a model predictive controller.

Boston Dynamics shows its Atlas humanoid robots running a parkour course with jumps, balance beams and vaults, demonstrating whole-body athletic control.

A short Boston Dynamics clip of the Sand Flea, an 11-pound RC-car-style robot that can jump about 30 feet into the air. An onboard stabilization system keeps it oriented in flight and for landings.

A short Boston Dynamics clip of the Atlas humanoid robot doing parkour, jumping over a log and leaping up steps using whole-body control and computer vision to locate markers.

A short Boston Dynamics demo of Handle, a wheeled mobile manipulation robot that builds and unloads mixed-box pallets in a warehouse. It uses vision to find boxes and force control to place them against neighbors.

Boston Dynamics shows the electric Atlas autonomously moving engine covers between containers and a sequencing dolly. It uses an ML vision model and grasping policy with no teleoperation or prescribed motions.

A short Boston Dynamics demo of RHex, a 30-lb six-legged robot built for rough terrain, remotely operated with a video uplink and about four hours of battery life. It can run right-side-up or upside-down.

A short Boston Dynamics clip of the DARPA-funded Cheetah quadruped robot hitting 28.3 mph on a treadmill, slightly faster than Usain Bolt's fastest 20 meter split.

Boston Dynamics' New Year video shows its Atlas, Spot and Handle robots dancing to 'Do You Love Me?'. It showcases the company's progress in legged dynamic balance.

Boston Dynamics unveils a new, smaller Atlas humanoid robot that is electrically powered and hydraulically actuated. It balances with body sensors and uses lidar and stereo vision to navigate and manipulate objects.

Boston Dynamics shows WildCat, a four-legged robot built with DARPA funding that reached about 19 mph using bounding and galloping gaits.

A 3-minute demo of a tiny IOCCC 2012 winning C program that simulates fluid dynamics in an 80x25 terminal, using any text (including its own source) as input. The video shows the simulation running to Handel's Water Music.

NightHawkInLight demonstrates how a Tesla valve works by sending a propane flame front through one, making the flow visible. It is a short, hands-on experiment video.

A one-minute clip from Cambridge's Prof. Holger Babinsky that debunks the equal transit time explanation of lift. It shows how air actually flows over a wing.

A short Dyalog demonstration building Conway's Game of Life in a single line of APL, step by step. It shows how array operations replace loops.

Jonathan Blow demos his prototype programming language, covering the base language and compile-time execution, including running a game while compiling. The video is about 70 minutes of demo followed by Q&A.

Peter Sripol builds and flies an RC aeroplane whose wings are rotating KFC buckets, using the Magnus effect (Flettner rotors) for lift. It is a hobbyist experiment in unconventional aerodynamics.

Short footage of the General Electric Cybernetic Anthropomorphous Machine, or Walking Truck, a 1960s quadruped vehicle operated by a human driver using hydraulic limbs. The uploader notes it predates Big Dog by decades.

A short clip of the Sprint anti-ballistic missile, which was launched from a silo and reached Mach 10 within seconds. Its nose and skin glow white hot from aerodynamic heating.

Ruby developer Avdi Grimm gives a seven-minute tour of Pharo Smalltalk's development environment, focusing on tools like search-by-example and the integrated, live coding experience.

A five-minute lightning demo of VisiData, a terminal tool for exploring and manipulating data. It uses two months of NYC 311 complaint data to drill down, plot points on a virtual map and save selected rows.

An overview of the PTVS 2.0 beta feature for debugging Python and C/C++ together in one session in Visual Studio.

David Heinemeier Hansson builds a blog engine with Ruby on Rails in 15 minutes, the demo that launched Rails' momentum.

A 1975 live demonstration of the APL language by Imperial College professor Bob Spence, showing a REPL on a modified typewriter terminal and APL's appeal to non-programmers.

A short Veritasium video showing how far a backspinning basketball would travel dropped off a dam. It demonstrates the Magnus effect and links to Flettner rotor ships and aircraft.

A 12-minute film in which Erlang's creators demonstrate the language's fault tolerance and live-system features, including phoning each other to show it working. This version has fixed audio.

A short comparison of the retail release of Metallica's Death Magnetic against the Guitar Hero 3 version of the same song. It switches between the two so you can hear and see the heavy clipping in the retail master.

A short compilation of aircraft flying through clouds and moist air, showing the spiraling vortices that wings leave behind. The footage shows wingtip vortices and the way planes disturb cloud layers.

Arend Schwab demonstrates a research bicycle, the two-mass-skate design, that balances itself without gyroscopic effects or trail. It challenges the common explanations for why a moving bicycle stays upright.

Scott Manley uses a realistically scaled Kerbal Space Program setup to show why dropping something into the Sun is far harder than it sounds. It demonstrates the need to cancel orbital velocity.
