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.

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.

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 short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

Hungarian folk dancers from Sapientia University act out the quicksort algorithm step by step, with music. It is part of the AlgoRythmics series of sorting algorithms performed as dance.

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.

Scott Manley's short animation shows every asteroid discovery from 1970 to 2015 plotted over time in 8K. It makes visible how survey technology made discoveries accelerate and where telescopes looked.

Physics Girl shows a vortex phenomenon (a falaco soliton) that can be reproduced in a pool on a sunny day. Two vortices are created with plates and made visible with food coloring.

Henry Segerman and collaborators demonstrate virtual reality experiences in non-Euclidean spaces, including hyperbolic and mixed hyperbolic-Euclidean geometry. The browser-based demos let viewers move through these spaces and show how strange the geometry feels from inside.

Bruce Hauman live-codes Flappy Bird in ClojureScript in about six minutes, using figwheel to hot-reload changes into the running game. The demo shows game behavior being changed interactively without restarting.

AvE tears down a roughly $500 Dyson hair dryer, examining how its motor, airflow and electronics fit into a small body. He runs tests along the way and ultimately decides whether the engineering justifies the price.

Corridor Digital makes a roughly seven-minute anime short using Stable Diffusion and related AI tools, based on a technique they teach in a longer tutorial. It was an early showcase of AI-assisted animation.

Grant Sanderson of 3Blue1Brown shows his workflow for animating math videos with Manim, with Ben Sparks. He codes scenes live, including a Lorenz attractor, and walks through example scenes.

A short visualization from HotNets researchers of routing and latency over SpaceX's proposed Starlink constellation, based on its FCC filings. It shows orbital shells, link topology and how inter-satellite routes could beat terrestrial fiber on long distances.

Alan Kay demonstrates GRaIL, a graphical input language system from around 1968 in which hand-drawn strokes become boxes, connections and dataflow-style programs.

The author of lazygit demos 15 features of his terminal UI for git, such as staging individual lines and easier rebasing, aimed at making common git tasks simpler.

Der8auer tours Hetzner's test lab and shows a custom AM5 server motherboard with the CPU socket rotated 90 degrees, built for rack airflow in their AX52 servers.

debuglive makes a 1990-style dance track on an Amiga 500 with a Stereo Master sampler and cheap secondhand records, showing how sampling and trackers worked within tight memory limits.

Bob Nystrom shows his process for hand-drawing the diagrams in his book Crafting Interpreters, from pencil sketches to tracing and inking. It is a time-lapse of the whole illustration workflow.

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 49-minute demo of Palantir Foundry by its chief architect. It walks through data integration, ML and AI workflows, analytics, and application building across the platform.

A short demo of interactive AI live painting in Krita using the Stable Diffusion plugin, where canvas changes update the generated image immediately. It uses an LCM sampler for speed and needs a high-end GPU for the interactive feel.

A one-minute visualization of a simulated ant colony in which ants follow pheromone trails, with the source code on GitHub. It shows emergent behavior arising from simple rules.

CNLohr maps Wi-Fi signal strength at high resolution by moving an ESP8266 on a CNC mill, then visualizes the 3D data in WebGL. The result shows interference patterns in space.

A NASA and Durham University supercomputer simulation suggesting the Moon may have formed within hours of a giant impact between Earth and a Mars-sized body. It is one of the highest-resolution giant-impact simulations run.

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

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.
