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.

A short look at the Voder, the first electronic voice synthesizer, demonstrated by Bell Labs at the 1939 World's Fair. It was operated by trained women using ten finger keys, foot pedals and a knee lever.

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.

SethBling shows MarI/O, a program using neural networks and the NEAT genetic algorithm to learn to play Super Mario World. The description links the source code, the paper and background reading.

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.

Sebastian Lague explores an ant-inspired algorithm and simulates ant and slime mold behavior, using compute shaders. Source code for both simulations is available.

Symbolics developer Kalman Reti gives a short introductory demo of a Symbolics Lisp Machine running Genera in an emulator. It shows the context-aware command line, typed on-screen objects, and the live-editable system, including swapping in a C-compiled JPEG decoder.

Overdrive 2 by TiTAN, a Sega Mega Drive demo that won first place in the Oldskool competition at Revision 2017. It shows effects and 3D graphics on the stock console.

Viznut demonstrates bytebeat, experimental music generated by extremely short C programs. It is the first of a series of videos on the technique.

Sentdex demonstrates GAN Theft Auto, a GameGAN-based neural network that recreates GTA V so the network itself is the playable environment. He shows the results and releases the code.

Mark Rober and Jabril build an app that uses machine learning to decode baseball sign sequences. The video also explains neural networks in a simple, accessible way.

Saqib Shaikh, a blind developer, shows how he writes and debugs code in Visual Studio 2017 using a screen reader. The short demo shows an expert doing ordinary developer tasks.

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.

A short demo of SEdit, the structure editor for Interlisp-D on Xerox Lisp machines in the 1980s, which edits code as trees rather than text.

A five-minute video showing how to build a counter in the Imba web programming language in under a minute, then style it.

A demonstration of loading Altair 4K BASIC on an Altair 8800 clone, using a front-panel bootloader and an ASR-33 Teletype. It shows the full sequence of entering boot code, loading BASIC and running a program.

A GameTrailers walkthrough from E3 2012 of an Unreal Engine 4 real-time tech demo with Epic's Alan Willard. It shows live code changes and hot reloading while the game runs.
