A one-minute New Scientist clip showing a Japanese experiment in which drivers on a circular track produce a spontaneous traffic jam that travels backward. It illustrates phantom traffic jams without any obstacle.

A short social experiment video in which people mimic the New York subway practice of workers pointing at signs and signals. It makes the point cheerfully.

A sped-up two-minute view of morning rush hour at a busy Utrecht junction, where thousands of bicycles and buses pass each day. It illustrates a city where about a third of trips are by bike.

A short research demo of Autonomous Intersection Management, a protocol in which self-driving cars reserve slots through an intersection instead of obeying signals or stop signs. It uses UT Austin's autonomous vehicle Marvin and a simulation to show cars crossing without stopping.

A short video of railroad workers in Storfors, Sweden, using thermite to weld rail sections together.

A Fully Charged episode where Robert Llewellyn visits an Oxford street trialling Urban Electric's pop-up chargers. These are retractable 7kW charging points built into street furniture for homes without off-street parking.

A one-minute clip of slime mold placed on a map with food at the cities around Tokyo, growing a network that approximates the Tokyo-area railway system.

A two-minute video of an athlete sprinting against a London Underground Circle Line train between Mansion House and Cannon Street. It shows a runner keeping pace with and beating the train.

A Fully Charged episode on Ubitricity, a German company that turns ordinary street lamp posts into roughly 5 kW overnight EV charge points, with a locking cable and managed billing.

Cities: Skylines experiment measuring traffic flow across 30 different four-way junction designs, comparing vanilla traffic AI with the TMPE mod.

A short Streetfilms montage of Vredenburg in Utrecht, a car-free street carrying about 33,000 cyclists a day. It shows heavy bike traffic alongside pedestrians and buses.

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.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

Techmoan demonstrates the Tefifon, a vintage German audio player that combines elements of record and tape with a grooved elastic loop. He shows how it works and plays it.

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.

A two-minute demo of SmartKnob View, an open-source input knob built from a brushless gimbal motor, magnetic encoder and round LCD. Closed-loop torque control gives software-defined detents and end stops.

A two-hour complete longplay of the 1993 MS-DOS puzzle game The Incredible Machine, in which players assemble Rube Goldberg contraptions to complete simple tasks.

A short demo from the Ishikawa Komuro Lab of a high-speed robot hand paired with a 1000fps vision system performing dexterous manipulation. It shows what very low-latency vision and actuation can do.

A brief demonstration of a railroad tank car imploding after a vacuum is pulled with its safety valves disabled.

Kitboga builds an elaborate automated phone maze with fake captchas, hold loops and absurd support to trap scammers for days. It also covers how this protects potential victims by wasting scammers' time.
