A 2006 promotional video for sCrAmBlEd?HaCkZ!, a music software project that analyzes and reassembles sampled audio and video in real time, tied to themes of sampling and copyright.

Jim Pavloff rebuilds The Prodigy's 'Voodoo People' in Ableton from its listed samples. The video shows how the track is assembled and how close a handmade reconstruction can sound.

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.

AlphaPhoenix shows off a new camera that films at two billion frames per second and uses it to film a laser pointer pulse. He investigates a strange quirk in how the speed of light appears on camera.

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.

Onslaught's Bad Apple 64 is a Commodore 64 demo that streams over 2000 frames of the Bad Apple animation from a single disk side at 12fps, with each frame packed to around 70 bytes.

MIT researchers show that sound can be recovered from silent video by analyzing tiny vibrations in objects such as a potato chip bag. It works even with consumer cameras by using rolling shutter.

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 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.

A spectrogram analysis of Aphex Twin's track commonly called [Equation] from Windowlicker, rendered from a lossless version. At about 5:30 the spectrogram reveals an image of Richard D. James's face.

A short demonstration of radioteletype (RTTY), a digital communication mode used in amateur radio, showing what the signal sounds like.

A six-minute clip of Adobe's MAX 2011 sneak peek showing a Photoshop prototype that removes motion blur from photos. The audience reacts with astonishment as blurry images become legible.

Shahriar of The Signal Path tears down and experiments with Keysight's UXR real-time oscilloscope, which offers 110GHz bandwidth and 256GS/s sampling, and compares architectures from Keysight, LeCroy and Tektronix.
