AngeTheGreat describes building a physically realistic internal combustion engine simulator in C++, drawing on fluid dynamics, physics and chemistry. It generates procedural audio for engines such as a V8.

Primer simulates green beard altruism, where individuals recognize and help others carrying a shared marker, and shows how imposters affect its evolution. It is an animated evolution simulation based on published papers.

A short documentary about Eric Maundu's Arduino-controlled aquaponics setup in West Oakland, where contaminated soil rules out ordinary farming. Fish and circulating water grow plants without soil.

Rick Beato discusses a theory of why some children develop perfect pitch, based on early exposure to music. He draws on his experience with his own children.

A five-minute demo of a live ClojureScript game editor by Chris Granger. It is based on Bret Victor's demo from the Inventing on Principle talk, with code changes reflected instantly in the running game.

A ten-minute clip from Jonathan Blow's talk on preventing the collapse of civilization, arguing that software quality and the knowledge to build it are in decline.

A Gource visualization of 826 days of Minecraft development, from alpha 1.2 to release 1.5, condensed into eight minutes. Each dot is a file, folders are links, and developers fly around zapping files as they work on them.

A video showing a virtual camera built in Blender that simulates lenses and film layers using path tracing, to make physically modeled photographs.

Dr. John McDougall argues at TEDxFremont that starch-based diets are what humans were born to eat, drawing on 40 years of nutrition and disease work.

Hans Rosling and his son Ola run an audience quiz with global population, health and income data to show how wrong most people are about the world. Ola then gives four ways to get less ignorant.

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

Kurzgesagt makes a selfish case for improving the world, arguing that helping people far away raises prosperity and innovation for everyone, including yourself. The animated video frames this as egoistic altruism and positive-sum cooperation.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

Making-of video about ROM City Rampage, the NES version of Retro City Rampage, covering how the game's core was crunched to run on real 8-bit hardware and how NES games are made.
