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.

Gary Garrett's stop-motion animation of his song Flying Dream, with notes arranged on a lattice of fifths and major thirds. It shows how harmony looks in just intonation, inspired by Harmonic Experience.

A two-minute demonstration of the loudness war, showing how heavy dynamic range compression in CD mastering makes music louder while degrading sound quality. It uses audio examples so you can hear the distortion.

A spectrogram visualization of the sounds in a dial-up modem handshake, with an annotated image explaining each noise. It shows how the handshake's tones map to the negotiation steps.

An animation presenting a non-standard helical or vortex model of the solar system, in which the planets trail the Sun through space instead of orbiting in flat circles. The model is a non-conventional view that the author says differs from standard diagrams.

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.

Corridor Digital's comedic fake video of a Boston Dynamics robot fighting back against its human tormentors, made with motion capture and VFX.

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.

A short film made with cold neutron imaging at the Paul Scherrer Institut showing a moka pot brewing coffee, sped up four times. The neutron beam makes the water and steam inside the pot visible.

Jerobeam Fenderson shows how to draw a mushroom on an oscilloscope in XY mode using stereo audio, then animates it by modulating with a larger wave. Pd and Max4Live patches are provided.

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 short animation reconstructing a planet's looping orbit using Ptolemy's epicycles and deferents, with the epicycles tracing out the face of Homer Simpson. It shows how enough circles can reproduce nearly any shape.

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.
