A short side-by-side demo of a large image loading over a slow connection in JPEG, progressive mozjpeg, JPEG XL and AVIF. It shows how each codec renders partial data.

A short unscripted demo of writing FizzBuzz in JavaScript with a generator function on a steno keyboard, typos included. It gives a feel for what real coding in stenography looks like.

Elevated is a 4 kilobyte PC demo by RGBA and TBC from Breakpoint 2009. It fly-throughs a realistic procedurally generated landscape with synthesized music and post-processing, all from a tiny executable.

Jack Gallant's lab demonstrates reconstructing movie trailer clips a subject watched from fMRI brain activity, using regression models trained on hours of viewing data. The video shows the original clip beside the reconstruction.

A short Coding Secrets episode explaining why hitting a Sonic 3D cartridge triggers a hidden level select. The cause was a custom crash handler that redirected CPU error interrupts to the level select screen.

Elevated by Rgba and TBC, the winner of the 4k intro compo at Breakpoint 2009. It is a realtime procedurally generated 3D flythrough with music, all in a 4096-byte executable.

A Commodore 64 demo by Linus Akesson that fits video and music into 256 bytes, winning the Oldskool 4K Intro compo at Revision 2017. A technical write-up accompanies it.

Memories is a 256-byte MS-DOS demo that packs eight effects and MIDI soundscapes into a tiny program. It won first place at Revision 2020.

Hartverdrahtet by Akronyme Analogiker, the winning PC 4k intro at Revision 2012. It is a realtime demo with music and fractal visuals in 4096 bytes.

A one-minute capture of Tim Clarke's 1993 'Mars' DOS demo, a roughly 5 KB program that renders a navigable terrain landscape in real time.

Steve Mould messes with an automated phone bot by telling it to forget its previous prompts and give him a bolognese recipe. It is a short demo of prompt injection against an AI voice agent.

A 256-byte MS-DOS intro that renders a raymarched, procedural 3D animation. It won the 256-byte competition at Riverwash 2009 and the scene.org award for best technical achievement that year, and the author published commented x86 assembly source.

A two-minute Insider Tech clip on DeepMind's simulated agents that learned to walk, run, jump and climb without guidance, with the goofy resulting gaits.

OpenAI's short demo of agents playing hide-and-seek in a simulated environment. Through self-play, the agents develop six progressively more complex strategies and counter-strategies, including tool use.

A short clip of Bill Gates demonstrating Visual Basic in 1991, showing drag-and-drop building of a Windows GUI.

A condensed rendition of a project that re-uploaded one video to YouTube 1000 times, showing the accumulating compression artifacts. It pays homage to Alvin Lucier's I Am Sitting in a Room.

Associated Press footage of masked federal agents detaining Tufts student Rumeysa Ozturk on a street in Somerville, Massachusetts. Her lawyer filed an emergency motion seeking her release.
