A long documentary-style video arguing that slavery in the US effectively continued through convict leasing and the prison system until around 1942. It covers the constitutional carveout and the history of neoslavery.

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.

A Computerphile video in which Dr Mike Pound and PhD student Lewis Stuart explain 3D Gaussian splatting, a quick technique that turns photos of a scene into a 3D model without much compute. It includes a demo and compares the approach to NeRFs.

A SIGGRAPH Asia 2013 research demo of 3-Sweep, a tool for extracting editable 3D objects from a single photo using a few user strokes. It predates modern AI image tools.

A half-hour television special on the 2007 fiery collapse of a connector in the Bay Area's MacArthur Maze and its rebuilding in 26 days. It was produced for the Professional Engineers in California Government.

Bungie's David Aldridge explains the networking programming behind Halo: Reach in a 2011 GDC session. It covers how gameplay stays in sync online, including forecasting and state reconciliation.

Jim Pavloff rebuilds the Prodigy track Smack My Bitch Up in Ableton, identifying the samples used and recreating the track by hand.

Linguist Simon Roper reconstructs how a London accent would have sounded from the 14th to the 21st centuries, reading passages in period pronunciation. It draws on the Cambridge History of the English Language.

A 98-minute LEMMiNO video reconstructing what happened inside the Texas School Book Depository before, during, and after the Kennedy assassination. It draws on testimony to map people's movements and discrepancies.

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.
